Let’s solve each equation step by step. We’re solving for x in each case — that means we want to get x alone on one side of the equals sign.

---

1) x + 12 = 14
→ Subtract 12 from both sides:
x = 14 - 12
x = 2

2) 11 + x = 15
→ Subtract 11 from both sides:
x = 15 - 11
x = 4

3) x - 5 = 6
→ Add 5 to both sides:
x = 6 + 5
x = 11

4) 2 + x = 8
→ Subtract 2 from both sides:
x = 8 - 2
x = 6

5) x - 3 = 2
→ Add 3 to both sides:
x = 2 + 3
x = 5

6) x - 6 = 6
→ Add 6 to both sides:
x = 6 + 6
x = 12

7) 7 + x = 14
→ Subtract 7 from both sides:
x = 14 - 7
x = 7

8) 12 - x = 7
→ This one is tricky! Let’s think:
We can rewrite it as: 12 - 7 = x (because if you take away x and get 7, then x must be what’s left when you subtract 7 from 12)
x = 5
*(Or: subtract 12 from both sides → -x = -5 → multiply both sides by -1 → x = 5)*

9) 5 + x = 9
→ Subtract 5 from both sides:
x = 9 - 5
x = 4

10) x - 10 = 2
→ Add 10 to both sides:
x = 2 + 10
x = 12

11) x + 6 = 14
→ Subtract 6 from both sides:
x = 14 - 6
x = 8

12) 7 + x = 10
→ Subtract 7 from both sides:
x = 10 - 7
x = 3

13) 10 - x = 7
→ Think: What do I subtract from 10 to get 7? That’s 3.
So x = 3
*(Or: subtract 10 → -x = -3 → x = 3)*

14) 8 + x = 16
→ Subtract 8 from both sides:
x = 16 - 8
x = 8

15) x - 9 = 1
→ Add 9 to both sides:
x = 1 + 9
x = 10

16) x + 10 = 14
→ Subtract 10 from both sides:
x = 14 - 10
x = 4

17) x - 3 = 8
→ Add 3 to both sides:
x = 8 + 3
x = 11

18) x + 7 = 9
→ Subtract 7 from both sides:
x = 9 - 7
x = 2

19) x + 7 = 19
→ Subtract 7 from both sides:
x = 19 - 7
x = 12

20) x + 2 = 10
→ Subtract 2 from both sides:
x = 10 - 2
x = 8
