- 8(4a - 4) - 1 = 14 - 8a
32a - 32 - 1 = 14 - 8a
32a - 33 = 14 - 8a
32a + 8a = 14 + 33
40a = 47
a = 47/40
- 4(-8x + 5) = -30x - 26
-32x + 20 = -30x - 26
-32x + 30x = -26 - 20
-2x = -46
x = 23
- 27 = 46 + 3x - x
27 = 46 + 2x
27 - 46 = 2x
-19 = 2x
x = -19/2
- 38 + 7k = 8(k + 4)
38 + 7k = 8k + 32
38 - 32 = 8k - 7k
6 = k
k = 6
- -2(4 - x) = 6(x + 4) + 4x
-8 + 2x = 6x + 24 + 4x
-8 + 2x = 10x + 24
-8 - 24 = 10x - 2x
-32 = 8x
x = -4
- 0.05z + 0.2 = 0.15z - 10.5
0.2 + 10.5 = 0.15z - 0.05z
10.7 = 0.10z
z = 107
- 4(6 + 4x) = 0
24 + 16x = 0
16x = -24
x = -3/2
- x/8 - x/9 = 1
(9x - 8x)/72 = 1
x/72 = 1
x = 72
