Step-by-step explanation:
23)
8m + 3(2+8m) = 6-6m
8m + 6 + 24m = 6-6m
32m + 6 = 6-6m
- 6 from both sides
32m = -6m
38m = 0
∴ m = 0
25)
-7 +x = 8x - 7(-7x +1)
-7 + x = 8x + 49x - 7
-7 + x = 57x - 7
+ 7 on both sides
x = 57x
∴ x = 0
27)
2(3n + 9) - 12 = -4(5 + 5n)
6n + 18 - 12 = -20 - 20n
6n + 6 = -20 - 20n
+ 20n on both sides
26n + 6 = -20
- 6 on both sides
26n = -26
∴ n = -1
