Let’s solve each problem step by step. We’re solving for the variable
y in each equation. That means we want to find what number y equals.
We’ll go one by one:
---
1.
y - 7 = -5
Add 7 to both sides:
y = -5 + 7 → y =
2
2.
4 + y = 5
Subtract 4 from both sides:
y = 5 - 4 → y =
1
3.
y + 5 = 14
Subtract 5 from both sides:
y = 14 - 5 → y =
9
4.
5 - y = -2
Subtract 5 from both sides:
-y = -2 - 5 → -y = -7
Multiply both sides by -1:
y =
7
5.
1 + y = 9
Subtract 1 from both sides:
y = 9 - 1 → y =
8
6.
y + 1 = 2
Subtract 1 from both sides:
y = 2 - 1 → y =
1
7.
3 + y = 8
Subtract 3 from both sides:
y = 8 - 3 → y =
5
8.
y - 9 = 0
Add 9 to both sides:
y = 0 + 9 → y =
9
9.
y + 5 = 7
Subtract 5 from both sides:
y = 7 - 5 → y =
2
10.
y - 3 = 0
Add 3 to both sides:
y = 0 + 3 → y =
3
11.
y + 8 = 10
Subtract 8 from both sides:
y = 10 - 8 → y =
2
12.
y + 9 = 13
Subtract 9 from both sides:
y = 13 - 9 → y =
4
13.
y + 8 = 16
Subtract 8 from both sides:
y = 16 - 8 → y =
8
14.
6 - y = 5
Subtract 6 from both sides:
-y = 5 - 6 → -y = -1
Multiply by -1:
y =
1
15.
y + 8 = 11
Subtract 8 from both sides:
y = 11 - 8 → y =
3
16.
y + 2 = 6
Subtract 2 from both sides:
y = 6 - 2 → y =
4
17.
y - 9 = -2
Add 9 to both sides:
y = -2 + 9 → y =
7
18.
7 - y = 3
Subtract 7 from both sides:
-y = 3 - 7 → -y = -4
Multiply by -1:
y =
4
19.
6 - y = 1
Subtract 6 from both sides:
-y = 1 - 6 → -y = -5
Multiply by -1:
y =
5
20.
8 - y = 4
Subtract 8 from both sides:
-y = 4 - 8 → -y = -4
Multiply by -1:
y =
4
21.
y - 5 = -3
Add 5 to both sides:
y = -3 + 5 → y =
2
22.
y - 1 = 7
Add 1 to both sides:
y = 7 + 1 → y =
8
23.
y + 8 = 15
Subtract 8 from both sides:
y = 15 - 8 → y =
7
24.
8 - y = -1
Subtract 8 from both sides:
-y = -1 - 8 → -y = -9
Multiply by -1:
y =
9
