(1) 2x - 3 = 5
2x = 5 + 3
2x = 8
x = 4

(2) 3x = 5x - 12
3x - 5x = -12
-2x = -12
x = 6

(3) 6x - 17 = -3x + 10
6x + 3x = 10 + 17
9x = 27
x = 3

(4) 4x + 12 = 7 - x
4x + x = 7 - 12
5x = -5
x = -1

(5) 5 - 4x = 2x -1
-4x - 2x = -1 - 5
-6x = -6
x = 1

(6) 3(x - 5) = -6
3x - 15 = -6
3x = -6 + 15
3x = 9
x = 3
