3x+8 = 5x+10
Take 3x away from both sides: 8 = 2x + 10
Take 10 away from both sides: -2 = 2x
Divide both sides by 2: -1 = x

5x - 10 = 3x + 2 5x - 3x = 2 + 10 2x = 12 x = 12/2 x = 6
122-5x = 3x+10 122-10 = 3x+5x 112 = 8x 112/8 = x x = 14
3x - 7 = 5x + 13-2x = 20x = -10
If: 3x-7 = 5x+13 Then: x = -10
x= 9
