Answer:
Answers are below.
Step-by-step explanation:
6x + 3x = 18
9x = 18
x = 2
-5x + 13x = 64
8x = 64
x = 8
6x - 5 + 7x = 34
13x - 5 = 34
13x = 39
x = 3
12 - 10x + 5x = -18
12 - 5x = -18
-5x = -30
x = 6
8x - 6x - 3 + 8 = 81
2x - 3 + 8 = 81
2x + 5 = 81
2x = 76
x = 38
-8x + 6x + 3 - 22 = 15
-2x + 3 - 22 = 15
-2x - 19 = 15
-2x = 34
x = -17
7x - 4x = 27
3x = 27
x = 9
-10x - 5x = 45
-15x = 45
x = -3
-15 + 3x - 7x = -43
-15 - 4x = -43
-4x = -28
x = 7
5x + 4x - 27 = 81
9x - 27 = 81
9x = 108
x = 12
