3x equals 5x-10 equals?
3x = 5x - 10 Subtract both sides by 5x 3x - 5x = 5x - 10 - 5x Simplify - 2x = - 10 Divided both sides by -2 to isolate x - 2x / - 2 = - 10 / - 2 Simplify x = 5 Plug x into the original equation. 3(5) = 5(5) - 10 = ? Simplify 15 = 25 - 10 = ? Simplify 15 = 15 = ? Therefore 3x = 5x - 10 = 15
