Question

What is the solution to the equation shown below?

-1/3(6x+6)+21=3y

Answer 1

Answer:

A or 19/5

Step-by-step explanation:

To solve first we isolate are variables so we distubte to get -2y-2+21=3y then we add 2y to the opposite side to get -2+21=5y. Then we add -2+21 to get 19 so are equation is 19=5y. Next we just divide 19 by 5 to get y=(19/5) or option A

Answer 2

-1/3(6y + 6)=3y-21
-6/3y - 6/3 = 3y-21 ( distribution)
-18y-18 = 3y - 21

-18y-18 = 27y - 189 ( cross product )
-18y - 27y= -189+18 (collecting like terms)
-45y = -171
——. ——- ( dividing both sides by 45 )
-45. -45.
y = 19
