Step-by-step solution for: Free Printable Color by Number for Adults - Algebra Coloring Pages
This is a "Color by Number" activity that involves solving algebraic equations to determine which color to use for each section of the image. Here's how to solve the problem step-by-step:
---
- Each section of the flower has an equation.
- Solve each equation to find the value of \( x \).
- Match the value of \( x \) to the corresponding number (3, 4, 5, 6, 7, 8, or 9) and use the provided color key to color the section.
We will solve each equation one by one and determine the value of \( x \).
#### Equation 1: \( 26 + -5x = 11 \)
\[
26 - 5x = 11
\]
Subtract 26 from both sides:
\[
-5x = 11 - 26
\]
\[
-5x = -15
\]
Divide by -5:
\[
x = 3
\]
#### Equation 2: \( 47 - 3x = 32 \)
\[
47 - 3x = 32
\]
Subtract 47 from both sides:
\[
-3x = 32 - 47
\]
\[
-3x = -15
\]
Divide by -3:
\[
x = 5
\]
#### Equation 3: \( 55 + 3x = 67 \)
\[
55 + 3x = 67
\]
Subtract 55 from both sides:
\[
3x = 67 - 55
\]
\[
3x = 12
\]
Divide by 3:
\[
x = 4
\]
#### Equation 4: \( 64 + -4x = 29 \)
\[
64 - 4x = 29
\]
Subtract 64 from both sides:
\[
-4x = 29 - 64
\]
\[
-4x = -35
\]
Divide by -4:
\[
x = 8.75 \quad (\text{Not in the given range})
\]
#### Equation 5: \( 73 + -3x = 55 \)
\[
73 - 3x = 55
\]
Subtract 73 from both sides:
\[
-3x = 55 - 73
\]
\[
-3x = -18
\]
Divide by -3:
\[
x = 6
\]
#### Equation 6: \( 6 + 3x = 15 \)
\[
6 + 3x = 15
\]
Subtract 6 from both sides:
\[
3x = 15 - 6
\]
\[
3x = 9
\]
Divide by 3:
\[
x = 3
\]
#### Equation 7: \( 157 + 11x = 69 \)
\[
157 + 11x = 69
\]
Subtract 157 from both sides:
\[
11x = 69 - 157
\]
\[
11x = -88
\]
Divide by 11:
\[
x = -8 \quad (\text{Not in the given range})
\]
#### Equation 8: \( 67 - 4x = 46 \)
\[
67 - 4x = 46
\]
Subtract 67 from both sides:
\[
-4x = 46 - 67
\]
\[
-4x = -21
\]
Divide by -4:
\[
x = 5.25 \quad (\text{Not in the given range})
\]
#### Equation 9: \( 102 - 12x = 66 \)
\[
102 - 12x = 66
\]
Subtract 102 from both sides:
\[
-12x = 66 - 102
\]
\[
-12x = -36
\]
Divide by -12:
\[
x = 3
\]
#### Equation 10: \( 44 - 2x = 30 \)
\[
44 - 2x = 30
\]
Subtract 44 from both sides:
\[
-2x = 30 - 44
\]
\[
-2x = -14
\]
Divide by -2:
\[
x = 7
\]
#### Equation 11: \( 85 - 2x = 67 \)
\[
85 - 2x = 67
\]
Subtract 85 from both sides:
\[
-2x = 67 - 85
\]
\[
-2x = -18
\]
Divide by -2:
\[
x = 9
\]
#### Equation 12: \( 103 - 4x = 71 \)
\[
103 - 4x = 71
\]
Subtract 103 from both sides:
\[
-4x = 71 - 103
\]
\[
-4x = -32
\]
Divide by -4:
\[
x = 8
\]
#### Equation 13: \( 34 + 5x = 64 \)
\[
34 + 5x = 64
\]
Subtract 34 from both sides:
\[
5x = 64 - 34
\]
\[
5x = 30
\]
Divide by 5:
\[
x = 6
\]
#### Equation 14: \( -4x + 7 = 43 \)
\[
-4x + 7 = 43
\]
Subtract 7 from both sides:
\[
-4x = 43 - 7
\]
\[
-4x = 36
\]
Divide by -4:
\[
x = -9 \quad (\text{Not in the given range})
\]
#### Equation 15: \( 76 + 2x = 86 \)
\[
76 + 2x = 86
\]
Subtract 76 from both sides:
\[
2x = 86 - 76
\]
\[
2x = 10
\]
Divide by 2:
\[
x = 5
\]
#### Equation 16: \( 109 - 4x = 73 \)
\[
109 - 4x = 73
\]
Subtract 109 from both sides:
\[
-4x = 73 - 109
\]
\[
-4x = -36
\]
Divide by -4:
\[
x = 9
\]
