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:

---

Step 1: Understand the Task


- The image contains a circular design divided into sections, each labeled with an algebraic equation.
- Solve each equation to find the value of \( x \).
- Match the value of \( x \) to the corresponding color code provided at the top of the page.

Step 2: Color Code Reference


The color codes are as follows:
- \( 3 = \text{blue} \)
- \( 4 = \text{pink} \)
- \( 5 = \text{purple} \)
- \( 6 = \text{red} \)
- \( 7 = \text{green} \)
- \( 8 = \text{orange} \)
- \( 9 = \text{yellow} \)

Step 3: Solve Each Equation


We will solve each equation one by one and determine the value of \( x \). Then, we'll match the value to the color code.

#### Equation 1: \( -2x + 59 = 41 \)
\[
-2x + 59 = 41
\]
Subtract 59 from both sides:
\[
-2x = 41 - 59
\]
\[
-2x = -18
\]
Divide by -2:
\[
x = \frac{-18}{-2} = 9
\]
Color: Yellow

#### Equation 2: \( 60 + 2x = 74 \)
\[
60 + 2x = 74
\]
Subtract 60 from both sides:
\[
2x = 74 - 60
\]
\[
2x = 14
\]
Divide by 2:
\[
x = \frac{14}{2} = 7
\]
Color: Green

#### Equation 3: \( 88 - 5x = 53 \)
\[
88 - 5x = 53
\]
Subtract 88 from both sides:
\[
-5x = 53 - 88
\]
\[
-5x = -35
\]
Divide by -5:
\[
x = \frac{-35}{-5} = 7
\]
Color: Green

#### Equation 4: \( 103 - 8x = 79 \)
\[
103 - 8x = 79
\]
Subtract 103 from both sides:
\[
-8x = 79 - 103
\]
\[
-8x = -24
\]
Divide by -8:
\[
x = \frac{-24}{-8} = 3
\]
Color: Blue

#### Equation 5: \( 1x + 64 = 67 \)
\[
1x + 64 = 67
\]
Subtract 64 from both sides:
\[
x = 67 - 64
\]
\[
x = 3
\]
Color: Blue

#### Equation 6: \( 65 + -4x = 29 \)
\[
65 - 4x = 29
\]
Subtract 65 from both sides:
\[
-4x = 29 - 65
\]
\[
-4x = -36
\]
Divide by -4:
\[
x = \frac{-36}{-4} = 9
\]
Color: Yellow

#### Equation 7: \( 23 + 4x = 55 \)
\[
23 + 4x = 55
\]
Subtract 23 from both sides:
\[
4x = 55 - 23
\]
\[
4x = 32
\]
Divide by 4:
\[
x = \frac{32}{4} = 8
\]
Color: Orange

#### Equation 8: \( -4x + 49 = 55 \)
\[
-4x + 49 = 55
\]
Subtract 49 from both sides:
\[
-4x = 55 - 49
\]
\[
-4x = 6
\]
Divide by -4:
\[
x = \frac{6}{-4} = -1.5
\]
Since this value does not match any of the given color codes, it might be an error or an outlier. For now, we'll note it as "No Color."

#### Equation 9: \( 129 + -13x = 38 \)
\[
129 - 13x = 38
\]
Subtract 129 from both sides:
\[
-13x = 38 - 129
\]
\[
-13x = -91
\]
Divide by -13:
\[
x = \frac{-91}{-13} = 7
\]
Color: Green

#### Equation 10: \( 31 + 4x = 79 \)
\[
31 + 4x = 79
\]
Subtract 31 from both sides:
\[
4x = 79 - 31
\]
\[
4x = 48
\]
Divide by 4:
\[
x = \frac{48}{4} = 12
\]
Since this value does not match any of the given color codes, it might be an error or an outlier. For now, we'll note it as "No Color."

#### Equation 11: \( 110 - 8x = 70 \)
\[
110 - 8x = 70
\]
Subtract 110 from both sides:
\[
-8x = 70 - 110
\]
\[
-8x = -40
\]
Divide by -8:
\[
x = \frac{-40}{-8} = 5
\]
Color: Purple

#### Equation 12: \( 71 - 4x = 39 \)
\[
71 - 4x = 39
\]
Subtract 71 from both sides:
\[
-4x = 39 - 71
\]
\[
-4x = -32
\]
Divide by -4:
\[
x = \frac{-32}{-4} = 8
\]
Color: Orange

#### Equation 13: \( 18 + 2x = 12 \)
\[
18 + 2x = 12
\]
Subtract 18 from both sides:
\[
2x = 12 - 18
\]
\[
2x = -6
\]
Divide by 2:
\[
x = \frac{-6}{2} = -3
\]
Since this value does not match any of the given color codes, it might be an error or an outlier. For now, we'll note it as "No Color."

#### Equation 14: \( 71 + 1x = 74 \)
\[
71 + x = 74
\]
Subtract 71 from both sides:
\[
x = 74 - 71
\]
\[
x = 3
\]
Color: Blue

#### Equation 15: \( 6 + 3x = 44 \)
\[
6 + 3x = 44
\]
Subtract 6 from both sides:
\[
3x = 44 - 6
\]
\[
3x = 38
\]
Divide by 3:
\[
x = \frac{38}{3} \approx 12.67
\]
Since this value does not match any of the given color codes, it might be an error or an outlier. For now, we'll note it as "No Color."

#### Equation 16: \( 29 + 5x = 23 \)
\[
29 + 5x = 23
\]
Subtract 29 from both sides:
\[
5x = 23 - 29
\]
\[
5x = -6
\]
Divide by 5:
\[
x = \frac{-6}{5} = -1.2
\]
Since this value does not match any of the given color codes, it might be an error or an outlier. For now, we'll note it as "No Color."

#### Equation 17: \( 5 + 3x = 23 \)
\[
5 + 3x = 23
\]
Subtract 5 from both sides:
\[
3x = 23 - 5
\]
\[
3x = 18
\]
Divide by 3:
\[
x = \frac{18}{3} = 6
\]
Color: Red

#### Equation 18: \( -1x + 21 = 18 \)
\[
-1x + 21 = 18
\]
Subtract 21 from both sides:
\[
-1x = 18 - 21
\]
\[
-1x = -3
\]
Divide by -1:
\[
x = \frac{-3}{-1} = 3
\]
Color: Blue

#### Equation 19: \( 32 + 4x = 60 \)
\[
32 + 4x = 60
\]
Subtract 32 from both sides:
\[
4x = 60 - 32
\]
\[
4x = 28
\]
Divide by 4:
\[
x = \frac{28}{4} = 7
\]
Color: Green

#### Equation 20: \( 75 + 2x = 81 \)
\[
75 + 2x = 81
\]
Subtract 75 from both sides:
\[
2x = 81 - 75
\]
\[
2x = 6
\]
Divide by 2:
\[
x = \frac{6}{2} = 3
\]
Color: Blue

#### Equation 21: \( 120 + -7x = 65 \)
\[
120 - 7x = 65
\]
Subtract 120 from both sides:
\[
-7x = 65 - 120
\]
\[
-7x = -55
\]
Divide by -7:
\[
x = \frac{-55}{-7} \approx 7.86
\]
Since this value does not match any of the given color codes, it might be an error or an outlier. For now, we'll note it as "No Color."

#### Equation 22: \( 48 + 1x = 56 \)
\[
48 + x = 56
\]
Subtract 48 from both sides:
\[
x = 56 - 48
\]
\[
x = 8
\]
Color: Orange

#### Equation 23: \( -9 + 4x = 15 \)
\[
-9 + 4x = 15
\]
Add 9 to both sides:
\[
4x = 15 + 9
\]
\[
4x = 24
\]
Divide by 4:
\[
x = \frac{24}{4} = 6
\]
Color: Red

#### Equation 24: \( 39 + 3x = 54 \)
\[
39 + 3x = 54
\]
Subtract 39 from both sides:
\[
3x = 54 - 39
\]
\[
3x = 15
\]
Divide by 3:
\[
x = \frac{15}{3} = 5
\]
Color: Purple

#### Equation 25: \( 5x - 12 = 28 \)
\[
5x - 12 = 28
\]
Add 12 to both sides:
\[
5x = 28 + 12
\]
\[
5x = 40
\]
Divide by 5:
\[
x = \frac{40}{5} = 8
\]
Color: Orange

#### Equation 26: \( 71 + 3x = 86 \)
\[
71 + 3x = 86
\]
Subtract 71 from both sides:
\[
3x = 86 - 71
\]
\[
3x = 15
\]
Divide by 3:
\[
x = \frac{15}{3} = 5
\]
Color: Purple

#### Equation 27: \( 122 + -12x = 38 \)
\[
122 - 12x = 38
\]
Subtract 122 from both sides:
\[
-12x = 38 - 122
\]
\[
-12x = -84
\]
Divide by -12:
\[
x = \frac{-84}{-12} = 7
\]
Color: Green

#### Equation 28: \( 33 - 3x = 15 \)
\[
33 - 3x = 15
\]
Subtract 33 from both sides:
\[
-3x = 15 - 33
\]
\[
-3x = -18
\]
Divide by -3:
\[
x = \frac{-18}{-3} = 6
\]
Color: Red

#### Equation 29: \( 74 - 13x = 35 \)
\[
74 - 13x = 35
\]
Subtract 74 from both sides:
\[
-13x = 35 - 74
\]
\[
-13x = -39
\]
Divide by -13:
\[
x = \frac{-39}{-13} = 3
\]
Color: Blue

#### Equation 30: \( 2x + 18 = 26 \)
\[
2x + 18 = 26
\]
Subtract 18 from both sides:
\[
2x = 26 - 18
\]
\[
2x = 8
\]
Divide by 2:
\[
x = \frac{8}{2} = 4
\]
Color: Pink

#### Equation 31: \( 1x + 38 = 42 \)
\[
1x + 38 = 42
\]
Subtract 38 from both sides:
\[
x = 42 - 38
\]
\[
x = 4
\]
Color: Pink
