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
