Question

What value of y will make the equation 5(y-7) +4 = 9 true?

Answer 1

y=8

Explanation:

5(y-7)+4=9

5y-35+4=9

5y=40

y=8

Answer 2

y=8

Explanation:

Start by distributing the 5 to each term in the parentheses:

5(y-7)+4=9

5(y)-5(7)+4=9

5y-35+4=9

Combine like terms

5y-31=9

Add 31 to both sides

5y-31+31=9+31

5y=40

Divide both sides by 5

y=8
