Question

5(-y+1)=-8 solve the equation and verify the answer​

Answer 1

$5(-y+1) =-8 \\\\\implies 1-y =- \dfrac 85 \\\\\\\implies y =1 + \dfrac 85\\\\\\\implies y = \dfrac{13}5 \\\\\\\text{Checking:}\\\\\\5\left(- \dfrac{13}5 +1 \right)\\\\\\=5\left(-\dfrac{8}5 \right)\\\\\\=-8~ \checkmark$

Answer 2

Use distributive property first.

5(-y + 1) = -8

-5y + 5 = -8

-5y = -8 -5

-5y = -13

y = -13/-5

y = 13/5
