Question

Find the equivalent equation that results from adding 5 to both sides first and then multiplying

both sides by 2. Show each step. You do not have to solve the equation at the end.

Answer 1

5d = 30

Explanation:

1. first you need to add 5 to both sides

d-4+5 = 2+5

2. then you need to combine like terms

d+1 = 7

3. after that you have to multiply both sides by 5

5(d+1) = 7(5)

4. simplify

5d + 5 = 35

-5 -5

5d = 30
