Question

Can someone pls help me? :)

Example:
2x + 4x - 3x = 18
6x - 3x = 18 (2x + 4x = 6x)
3x = 18 (6x - 3x = 3x)
x = 6 (18 divided by 3 = 6)

Example:
10s - 4 = 7s + 8
10s - 7s = 8 + 4
3s = 12 (12 divided by 3 = 4)
s = 4

Directions: Solve each of the following equations.
a. Combine like terms
b. Then isolate the variable if necessary
c. Follow rules for signed numbers
1. 15t + 8t - 2t = 16
2. 24m + 24m = 96
3. 26 = 12n + 2n
4. 20a - 3a = 34
5. 170x + 4 = 64
6. 15x - 25 = 200
7. 5s + 3s = 42
8. 10t + 2t = 28
9. 14s + 35s - 7s = 42
10. 124s - 14s + 12s = 12
11. 76x + 23x = 33
12. 140r - 8r - 4r = 216
13. 98c - 99c = 1
14. 104mn + (-84mn) = 36
15. 118j - 234j = 234
