Answer:
y = -11/7
Step-by-step explanation:
8 = 4(7y + 13)
Distribute the 4 inside the parenthesis.
8 = 4*7y + 4*13
8 = 28y + 52
Subtract 52 from both sides.
-44 = 28y
Divide 28 from both sides.
y = -44/28
Simplify the fraction.
y = -11/7.
Proof:
8 = 4(7y + 13)
Substitute the value.
8 = 4(7(-11/7) + 13)
Multiply inside the parenthesis.
8 = 4(-11 + 13)
Add inside the parenthesis.
8 = 4(2)
Multiply.
8 = 8
