It looks like you've uploaded a worksheet titled "Simplifying Linear Expressions" with 10 problems involving simplifying algebraic expressions. Since I can't view images directly, I'll help you solve each problem step by step based on the text you provided.
Let me go through each problem and simplify the expressions:
---
Step-by-step:
- Distribute:
$$
3(2x) - 3(4) + 5(x) + 5(2) = 6x - 12 + 5x + 10
$$
- Combine like terms:
$$
(6x + 5x) + (-12 + 10) = 11x - 2
$$
✔ Answer: $ \boxed{11x - 2} $
---
Step-by-step:
- Distribute:
$$
2(8x) + 2(7) - 3(2x) - 3(1) + 4(2x) + 4(5) = 16x + 14 - 6x - 3 + 8x + 20
$$
- Combine like terms:
$$
(16x - 6x + 8x) + (14 - 3 + 20) = 18x + 31
$$
✔ Answer: $ \boxed{18x + 31} $
---
Step-by-step:
- Distribute:
$$
5(2x) + 5(6) + 9(2) - 9(4x) + 15 = 10x + 30 + 18 - 36x + 15
$$
- Combine like terms:
$$
(10x - 36x) + (30 + 18 + 15) = -26x + 63
$$
✔ Answer: $ \boxed{-26x + 63} $
---
Step-by-step:
- Distribute:
$$
4(5x) + 4(3) - 7(x) - 7(5) + 3(2x) - 3(3) = 20x + 12 - 7x - 35 + 6x - 9
$$
- Combine like terms:
$$
(20x - 7x + 6x) + (12 - 35 - 9) = 19x - 32
$$
✔ Answer: $ \boxed{19x - 32} $
---
Step-by-step:
- Distribute:
$$
\frac{2}{3}(6x) + \frac{2}{3}(2) - 3(x) - 3(2) + 2(3x) + 2(1)
= 4x + \frac{4}{3} - 3x - 6 + 6x + 2
$$
- Combine like terms:
$$
(4x - 3x + 6x) + \left(\frac{4}{3} - 6 + 2\right) = 7x + \left(\frac{4}{3} - 4\right)
= 7x + \left(\frac{4}{3} - \frac{12}{3}\right) = 7x - \frac{8}{3}
$$
✔ Answer: $ \boxed{7x - \frac{8}{3}} $
---
Step-by-step:
- Distribute:
$$
\frac{1}{2}x - 1 + \frac{2}{3}x - x
$$
- Combine like terms:
$$
\left(\frac{1}{2}x + \frac{2}{3}x - x\right) - 1
$$
- Find common denominator for coefficients:
$$
\frac{3}{6}x + \frac{4}{6}x - \frac{6}{6}x = \frac{1}{6}x
$$
- So:
$$
\frac{1}{6}x - 1
$$
✔ Answer: $ \boxed{\frac{1}{6}x - 1} $

Wait — this expression has two variables, $x$ and $y$, and includes a product of binomials.
But let's check: Is it $4(3x + 4)(2y - 1)$ or is there a typo?
Assuming it's meant to be simplified as written:
Step-by-step:
First, expand $ (3x + 4)(2y - 1) $:
$$
= 3x(2y) + 3x(-1) + 4(2y) + 4(-1) = 6xy - 3x + 8y - 4
$$
Now multiply by 4:
$$
4(6xy - 3x + 8y - 4) = 24xy - 12x + 32y - 16
$$
Now add $ 2(4xy + 2) = 8xy + 4 $
Add both parts:
$$
(24xy + 8xy) + (-12x) + 32y + (-16 + 4) = 32xy - 12x + 32y - 12
$$
✔ Answer: $ \boxed{32xy - 12x + 32y - 12} $
---
Again, two variables? But only $x$. Let's assume it's just $x$.
First, expand $ (x + 2)(2x - 1) $:
$$
= x(2x) + x(-1) + 2(2x) + 2(-1) = 2x^2 - x + 4x - 2 = 2x^2 + 3x - 2
$$
Multiply by $ \frac{1}{2} $:
$$
\frac{1}{2}(2x^2 + 3x - 2) = x^2 + \frac{3}{2}x - 1
$$
Now $ 3(6x + 3) = 18x + 9 $
Add:
$$
x^2 + \frac{3}{2}x - 1 + 18x + 9 = x^2 + \left(\frac{3}{2}x + 18x\right) + 8
= x^2 + \frac{39}{2}x + 8
$$
✔ Answer: $ \boxed{x^2 + \frac{39}{2}x + 8} $
Note: This is quadratic, not linear. If the original problem was supposed to be linear, double-check if there’s a typo.

Step-by-step:
- Distribute:
$$
\frac{3}{4}(6x) - \frac{3}{4}(18) + 8x - 12 + 2x
= \frac{18}{4}x - \frac{54}{4} + 8x - 12 + 2x
= \frac{9}{2}x - 13.5 + 8x - 12 + 2x
$$
- Convert to fractions:
$$
\frac{9}{2}x + 8x + 2x = \frac{9}{2}x + \frac{16}{2}x + \frac{4}{2}x = \frac{29}{2}x
$$
- Constants: $-13.5 - 12 = -25.5 = -\frac{51}{2}$
✔ Answer: $ \boxed{\frac{29}{2}x - \frac{51}{2}} $
Or write as: $ \boxed{\frac{29x - 51}{2}} $
---
Step-by-step:
- Distribute:
$$
8x + 12 - 6x + 12 + 6x - 15
$$
- Combine like terms:
$$
(8x - 6x + 6x) + (12 + 12 - 15) = 8x + 9
$$
✔ Answer: $ \boxed{8x + 9} $

1. $ 3(2x - 4) + 5(x + 2) $
Step-by-step:
- Distribute:
$$
3(2x) - 3(4) + 5(x) + 5(2) = 6x - 12 + 5x + 10

Step-by-step:
- Distribute:
$$
2(8x) + 2(7) - 3(2x) - 3(1) + 4(2x) + 4(5) = 16x + 14 - 6x - 3 + 8x + 20
$$
- Combine like terms:
$$
(16x - 6x + 8x) + (14 - 3 + 20) = 18x + 31
$$
✔ Answer: $ \boxed{18x + 31} $
---
3. $ 5(2x + 6) + 9(2 - 4x) + 15 $
Step-by-step:
- Distribute:
$$
5(2x) + 5(6) + 9(2) - 9(4x) + 15 = 10x + 30 + 18 - 36x + 15
$$
- Combine like terms:

4. $ 4(5x + 3) - 7(x + 5) + 3(2x - 3) $
Step-by-step:
- Distribute:
$$
4(5x) + 4(3) - 7(x) - 7(5) + 3(2x) - 3(3) = 20x + 12 - 7x - 35 + 6x - 9
$$
- Combine like terms:
$$
(20x - 7x + 6x) + (12 - 35 - 9) = 19x - 32
$$
✔ Answer: $ \boxed{19x - 32} $
---
5. $ \frac{2}{3}(6x + 2) - 3(x + 2) + 2(3x + 1) $
Step-by-step:
- Distribute:
$$
\frac{2}{3}(6x) + \frac{2}{3}(2) - 3(x) - 3(2) + 2(3x) + 2(1)
= 4x + \frac{4}{3} - 3x - 6 + 6x + 2
$$
- Combine like terms:
$$
(4x - 3x + 6x) + \left(\frac{4}{3} - 6 + 2\right) = 7x + \left(\frac{4}{3} - 4\right)
= 7x + \left(\frac{4}{3} - \frac{12}{3}\right) = 7x - \frac{8}{3}
$$
✔ Answer: $ \boxed{7x - \frac{8}{3}} $
---
6. $ \frac{1}{2}(x - 2) + \frac{2}{3}x + \frac{1}{2}(-2x) $
Step-by-step:
- Distribute:
$$
\frac{1}{2}x - 1 + \frac{2}{3}x - x
$$
- Combine like terms:
$$
\left(\frac{1}{2}x + \frac{2}{3}x - x\right) - 1
$$
- Find common denominator for coefficients:
$$
\frac{3}{6}x + \frac{4}{6}x - \frac{6}{6}x = \frac{1}{6}x
$$
- So:
$$
\frac{1}{6}x - 1
$$
✔ Answer: $ \boxed{\frac{1}{6}x - 1} $

7. $ 4(3x + 4)(2y - 1) + 2(4xy + 2) $
Wait — this expression has two variables, $x$ and $y$, and includes a product of binomials.
But let's check: Is it $4(3x + 4)(2y - 1)$ or is there a typo?
Assuming it's meant to be simplified as written:
Step-by-step:
First, expand $ (3x + 4)(2y - 1) $:
$$
= 3x(2y) + 3x(-1) + 4(2y) + 4(-1) = 6xy - 3x + 8y - 4
$$
Now multiply by 4:
$$
4(6xy - 3x + 8y - 4) = 24xy - 12x + 32y - 16
$$
Now add $ 2(4xy + 2) = 8xy + 4 $
Add both parts:
$$
(24xy + 8xy) + (-12x) + 32y + (-16 + 4) = 32xy - 12x + 32y - 12
$$
✔ Answer: $ \boxed{32xy - 12x + 32y - 12} $
---
8. $ \frac{1}{2}(x + 2)(2x - 1) + 3(6x + 3) $
Again, two variables? But only $x$. Let's assume it's just $x$.
First, expand $ (x + 2)(2x - 1) $:
$$
= x(2x) + x(-1) + 2(2x) + 2(-1) = 2x^2 - x + 4x - 2 = 2x^2 + 3x - 2
$$
Multiply by $ \frac{1}{2} $:
$$
\frac{1}{2}(2x^2 + 3x - 2) = x^2 + \frac{3}{2}x - 1
$$
Now $ 3(6x + 3) = 18x + 9 $
Add:
$$
x^2 + \frac{3}{2}x - 1 + 18x + 9 = x^2 + \left(\frac{3}{2}x + 18x\right) + 8
= x^2 + \frac{39}{2}x + 8
$$
✔ Answer: $ \boxed{x^2 + \frac{39}{2}x + 8} $
Note: This is quadratic, not linear. If the original problem was supposed to be linear, double-check if there’s a typo.

9. $ \frac{3}{4}(6x - 18) + 4(2x - 3) + 2x $
Step-by-step:
- Distribute:
$$
\frac{3}{4}(6x) - \frac{3}{4}(18) + 8x - 12 + 2x
= \frac{18}{4}x - \frac{54}{4} + 8x - 12 + 2x
= \frac{9}{2}x - 13.5 + 8x - 12 + 2x
$$
- Convert to fractions:
$$
\frac{9}{2}x + 8x + 2x = \frac{9}{2}x + \frac{16}{2}x + \frac{4}{2}x = \frac{29}{2}x
$$
- Constants: $-13.5 - 12 = -25.5 = -\frac{51}{2}$
✔ Answer: $ \boxed{\frac{29}{2}x - \frac{51}{2}} $
Or write as: $ \boxed{\frac{29x - 51}{2}} $
---
10. $ 4(2x + 3) - 3(2x - 4) + 3(2x - 5) $
Step-by-step:
- Distribute:
$$
8x + 12 - 6x + 12 + 6x - 15
$$
- Combine like terms:
$$
(8x - 6x + 6x) + (12 + 12 - 15) = 8x + 9
$$
✔ Answer: $ \boxed{8x + 9} $
---
