x = 1
Proof...
(- 3 from both sides)
5x = 5
(divide both sides by 5)
x = 1

5x-3 = 37 5x = 37+3 5x = 40 x = 8
5x + 5 = 8 -3x 5x = 3 -3x 8x = 3 x = 0.375
32-5x=3x+8 32-5x-8=3x+8-8 24-5x=3x 24-5x+5x=3x+5x 24=8x x=24/8=3
5x - 8 = 7 Add 8 to both sides 5x = 15 Divide both sides by 5 x = 3
-5x+3(x+8)=16-2x
