-2(4+7y)=-2(4+y)
We move all terms to the left:
-2(4+7y)-(-2(4+y))=0
We add all the numbers together, and all the variables
-2(7y+4)-(-2(y+4))=0
We multiply parentheses
-14y-(-2(y+4))-8=0
We calculate terms in parentheses: -(-2(y+4)), so:We get rid of parentheses
-2(y+4)
We multiply parentheses
-2y-8
Back to the equation:
-(-2y-8)
-14y+2y+8-8=0
We add all the numbers together, and all the variables
-12y=0
y=0/-12
y=0
