Let’s solve each equation one by one. We’ll isolate the variable
x on one side of the equation.
---
1. 21 + x = 26
Subtract 21 from both sides:
x = 26 - 21
x =
5
---
2. 12 + 2x = 16
Subtract 12 from both sides:
2x = 4
Divide both sides by 2:
x =
2
---
3. 4x - 2 = 10
Add 2 to both sides:
4x = 12
Divide by 4:
x =
3
---
4. x + 7 = 12
Subtract 7 from both sides:
x =
5
---
5. x + 15 = 28
Subtract 15 from both sides:
x =
13
---
6. 5x - 8 = 12
Add 8 to both sides:
5x = 20
Divide by 5:
x =
4
---
7. x - 13 = 24
Add 13 to both sides:
x =
37
---
8. x + 14 = -32
Subtract 14 from both sides:
x = -32 - 14
x =
-46
---
9. 4x - 2 = 14
Add 2 to both sides:
4x = 16
Divide by 4:
x =
4
---
10. 7x - 4 = 10
Add 4 to both sides:
7x = 14
Divide by 7:
x =
2
---
11. x + 19 = 21
Subtract 19 from both sides:
x =
2
---
12. x + 24 = 36
Subtract 24 from both sides:
x =
12
---
13. 9x - 18 = 9
Add 18 to both sides:
9x = 27
Divide by 9:
x =
3
---
14. 6x - 12 = 12
Add 12 to both sides:
6x = 24
Divide by 6:
x =
4
---
