To solve for the variable \( y \) in each equation, we will isolate \( y \) on one side of the equation. Let's go through a few examples step by step to illustrate the process.
General Steps:
1. Simplify both sides of the equation if necessary.
2. Move all terms involving \( y \) to one side and constants to the other side.
3. Solve for \( y \) by dividing or multiplying as needed.
Example Solutions:
#### Problem 1: \( 1y + 8 = 17 \)
\[
1y + 8 = 17
\]
Subtract 8 from both sides:
\[
1y = 17 - 8
\]
\[
1y = 9
\]
So, \( y = 9 \).
#### Problem 2: \( 59 = 8y + 3 \)
\[
59 = 8y + 3
\]
Subtract 3 from both sides:
\[
59 - 3 = 8y
\]
\[
56 = 8y
\]
Divide both sides by 8:
\[
y = \frac{56}{8}
\]
\[
y = 7
\]
#### Problem 3: \( 54 = 9 + 9y \)
\[
54 = 9 + 9y
\]
Subtract 9 from both sides:
\[
54 - 9 = 9y
\]
\[
45 = 9y
\]
Divide both sides by 9:
\[
y = \frac{45}{9}
\]
\[
y = 5
\]
#### Problem 4: \( 2 + 8y = 34 \)
\[
2 + 8y = 34
\]
Subtract 2 from both sides:
\[
8y = 34 - 2
\]
\[
8y = 32
\]
Divide both sides by 8:
\[
y = \frac{32}{8}
\]
\[
y = 4
\]
Continuing this process for all problems:
#### Problem 5: \( 61 = 5 + 7y \)
\[
61 = 5 + 7y
\]
Subtract 5 from both sides:
\[
61 - 5 = 7y
\]
\[
56 = 7y
\]
Divide both sides by 7:
\[
y = \frac{56}{7}
\]
\[
y = 8
\]
#### Problem 6: \( 5y + 7 = 47 \)
\[
5y + 7 = 47
\]
Subtract 7 from both sides:
\[
5y = 47 - 7
\]
\[
5y = 40
\]
Divide both sides by 5:
\[
y = \frac{40}{5}
\]
\[
y = 8
\]
#### Problem 7: \( 9 = 8 + y \)
\[
9 = 8 + y
\]
Subtract 8 from both sides:
\[
9 - 8 = y
\]
\[
y = 1
\]
#### Problem 8: \( 7 = 3y + 1 \)
\[
7 = 3y + 1
\]
Subtract 1 from both sides:
\[
7 - 1 = 3y
\]
\[
6 = 3y
\]
Divide both sides by 3:
\[
y = \frac{6}{3}
\]
\[
y = 2
\]
