Answer:
The answer to your question is below
Step-by-step 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
