To solve the first equation $3x + 8 = 29$:
1.
Subtract 8 from both sides to isolate the term with $x$:
$$
3x + 8 - 8 = 29 - 8
$$
$$
3x = 21
$$
2.
Divide both sides by 3 to solve for $x$:
$$
\frac{3x}{3} = \frac{21}{3}
$$
$$
x = 7
$$
The correct answer is
C. 7.

To solve the second equation $4x + 3 = 7$:
1.
Subtract 3 from both sides to isolate the term with $x$:
$$
4x + 3 - 3 = 7 - 3
$$
$$
4x = 4
$$
2.
Divide both sides by 4 to solve for $x$:
$$
\frac{4x}{4} = \frac{4}{4}
$$
$$
x = 1
$$
The correct answer is
A. 1.
---
To solve the third equation $3x - 5 = -26$:
1.
Add 5 to both sides to isolate the term with $x$:
$$
3x - 5 + 5 = -26 + 5
$$
$$
3x = -21
$$
2.
Divide both sides by 3 to solve for $x$:
$$
\frac{3x}{3} = \frac{-21}{3}
$$
$$
x = -7
$$
The correct answer is
B. -7.
---
To solve the fourth equation $2x - 12 = 5$:
1.
Add 12 to both sides to isolate the term with $x$:
$$
2x - 12 + 12 = 5 + 12
$$
$$
2x = 17
$$
2.
Divide both sides by 2 to solve for $x$:
$$
\frac{2x}{2} = \frac{17}{2}
$$
$$
x = 8.5
$$
The correct answer is
B. 8.5.
---
To solve the fifth equation $4x - 7 = 37$:
1.
Add 7 to both sides to isolate the term with $x$:
$$
4x - 7 + 7 = 37 + 7
$$
$$
4x = 44
$$
2.
Divide both sides by 4 to solve for $x$:
$$
\frac{4x}{4} = \frac{44}{4}
$$
$$
x = 11
$$
The correct answer is
A. 11.
---
To solve the sixth equation $33 = 4a - 7$:
1.
Add 7 to both sides to isolate the term with $a$:
$$
33 + 7 = 4a - 7 + 7
$$
$$
40 = 4a
$$
2.
Divide both sides by 4 to solve for $a$:
$$
\frac{40}{4} = \frac{4a}{4}
$$
$$
a = 10
$$
The correct answer is
A. a=10.
Final Answer:
1. C
2. A
3. B
4. B
5. A
6. A
