Question

Y/3 + 8 = -2 solve for y
a. -30
b. -18
c. 18
d. 30

Answer 1

`\large\boxed{a.\ -30}`

Explanation:

`(y)/(3)+8=-2\qquad\text{subtract 8 from both sides}\\\\(y)/(3)+8-8=-2-8\\\\(y)/(3)=-10\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot(y)/(3\!\!\!\!\diagup_1)=(3)(-10)\\\\y=-30`
