What are the steps to do - 2 (y+6) = y+3+2y

First of all, let's simplify the equations by adding and multiplying everything.

-2 (y+6) = y+3+2y

Add 2y and y on the right side:

-2 (y+6) = 3y+3

Distribute - 2y into the parentheses:

-2y - 12 = 3y + 3

Subtract both sides by - 2y - 12, so you have one side that equals zero:

5y + 15 = 0

Subtract both sides by 15:

5y = - 15

Divide both sides by 5:

y = - 3
