1. 4x + 5 = 2x – 3

2. 6 – (3 + x) = 7

3. -3 – 2x = 3(x +4)

4. x + (x – 5) = 25

5.
13
x – 1 = 5

6. 4x – 15 = 5(x – 3)

7. 3(x – 2) – 7 = 8

8. 2x – (3x + 1) = 6

9. 2(x +1) = x +8

10. 8(x+ 2) = 5(x+ 5)

11. 4 – x = 3(4 +x)

12. 2(x – 1) + 3(x – 2) = 7

13.
15 x – 5 = 8

14.

x + 10 = 24

15. x – 5 =
13
x + 1

16. 3(2 – 3x) = x – 4

17. 4(x + 3) + 8 = 36

18. 12x +7 = 9x + 10
