Pre-Algebra Addition Worksheet: Solve for the variable y in 16 simple equations.

Let’s solve each problem step by step. All problems are simple addition equations where we need to find the value of y.

We’ll use this idea:
If you have something like “A = B + y”, then to find y, you subtract B from A.
So, y = A - B

1. 14 = 5 + y → y = 14 - 5 = 9
2. 13 = 5 + y → y = 13 - 5 = 8
3. y + 3 = 6 → y = 6 - 3 = 3
4. 10 = y + 7 → y = 10 - 7 = 3
5. 12 = y + 4 → y = 12 - 4 = 8
6. 8 = y + 3 → y = 8 - 3 = 5
7. 9 = y + 4 → y = 9 - 4 = 5
8. 14 = 9 + y → y = 14 - 9 = 5
9. y + 1 = 7 → y = 7 - 1 = 6
10. 3 + y = 9 → y = 9 - 3 = 6
11. y + 1 = 10 → y = 10 - 1 = 9
12. y + 6 = 7 → y = 7 - 6 = 1
13. 1 + y = 3 → y = 3 - 1 = 2
14. y + 8 = 17 → y = 17 - 8 = 9
15. y + 7 = 15 → y = 15 - 7 = 8
16. 4 + y = 11 → y = 11 - 4 = 7
