Question

Explain two ways you could solve 20 = 5(-3 + x)

Answer 1

The answer to your question is below

Explanation:

First way

20 = 5(-3 + x) expand

20 = -15 + 5x simplify like terms

5x = 20 + 15

5x = 35 divide both sides by 5

5x/5 = 35/5

x = 7

Second way

20/5 = 5/5 (-3 + x) Divide both sides by 5

4 = -3 + x Add +3 in both sides

4 + 3 = -3 + 3 + x Simplify like terms

7 = x
