What are the correct steps in solving the following equation: -5(x - 2) = 30

• divide both sides by 5 and then add 2 to both sides

• divide both sides by -5 and then add 2 to both sides

• distribute the -5 to both terms inside the parentheses and then add 10 to both sides

• distribute -5 to both terms in the parentheses and then add 2 to both sides

Answer explanation

1) Look at the answer choices

2) Try the first step

3) Be sure to look at the second step in the answer choice and compare with what you would do to solve it

So you must try

1) distributing and check what the next step would be

2) dividing by the front number and then seeing what the next step would be
