Answer:

y = 8

Explanation:

Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

First, add 5 to both sides of the equation:

7y - 5 = 51

7y - 5 (+5) = 51 (+5)

7y = 51 + 5

7y = 56

Next, divide 7 from both sides of the equation:

(7y)/7 = (56)/7

y = 56/7

y = 8

8 is your answer for y.
