Question

What is the solution to the following equation?
-50 = -5x - 3(5x + 15)

Answer 1

The answer is x= 1/4

Answer 2

Explanation:

-50 = -5x - 3(5x + 15) {Use distributive rule}

-50 = -5x + 5x *(-3) + 15*(-3)

-50 = -5x - 15x - 45 {Combine like terms}

-50 = -20x - 45 {Add 45 to both sides}

-50 + 45 = -20x

-5 = -20x {Divide both sides by -20}

-5/-20 = x

1/4 = x
