Question

Solve for y:

9y = 36

A) y=4

B)y=12

C)y=18

D) y=9

Answer 1

A) y=4
A letter by the number means it wants you to multiple. So 9y = 36 means 9 x y = 36. Y=4 in that equation would mean 9 x 4 = 36 and it does so that is the answer

Answer 2

y=4

Explanation:

9y=36

first divide both sides by 9 (9y/9) and (36/9)

y=4

Now test that it is correct by replacing y with 4

9(4)=36

Indeed!
