1) 14x + 7 = 2(3x - 5) - 7
14x + 7 = 6x - 10 - 7
14x + 7 = 6x - 17
14x - 6x = -17 - 7
8x = -24
x = -24 / 8
x = -3

2) 15x - 27 = 5(x - 1)
15x - 27 = 5x - 5
15x - 5x = 27 - 5
10x = 22
x = 22 / 10
x = 11 / 5

3) 3x - 8 = 2(1 - x)
3x - 8 = 2 - 2x
3x + 2x = 2 + 8
5x = 10
x = 10 / 5
x = 2

4) 3(3x + 7) = 5x + 5
9x + 21 = 5x + 5
9x - 5x = 5 - 21
4x = -16
x = -16 / 4
x = -4

5) 2(5x - 10) = 8x + 5
10x - 20 = 8x + 5
10x - 8x = 5 + 20
2x = 25
x = 25 / 2
x = 12.5
