X = 1
-3x + 5 = 20 -3x = 15 x = -5
3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
no
3x + 5 = 20 Subtract '5' from both sides 3x = 15 Divide both sides by '3' x = 5 The answer!!!!!
3x+5=20 x=5 since 5x3+5=20
3x+12x = 15 15x = 15 x = 1
x = 15
x+5 = 3x+15 x-3x = 15-5 -2x = 10 x = -5
8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3
x=5
3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4
4x+7-3x = 15 4x-3x = 15-7 x = 8
