Question

Solve for the value of Y.
90=7y+8+8y+7

Answer 1

y = 5

Explanation:

1) Simplify 7y+8+8y+7 to 15y + 15.

90 = 15y + 15

2) Subtract 15 from both sides.

90 - 15 = 15y

3) Simplify 90 - 15 to 75.

75 = 15y

4) Divide both sides by 15.

75/15 = y

5) Simplify 75/15 to 5.

5 = y

6) Switch sides.

y = 5
