Question

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

Answer 1

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
