The answer is 3.

Step-by-step explanation:

Since you do the parentheses first, you will figure out what why is. Y = 3, because 3*3 =9, and 9-9=0.

Answer 2

Answer:

y = 3

Step-by-step explanation:

3(3y − 9) = 0

To solve the above do the following:

Divide both side by 3, we have:

3y — 9 = 0

Next, collect like terms

3y = 9

Next, divide both side by the coefficient of y i.e 3

y = 9/3

y = 3
