5-2y-3y-6=7y+11-\left(3y-6\right)
To find the opposite of 3y+6, find the opposite of each term.
5-5y-6=7y+11-\left(3y-6\right)
Combine -2y and -3y to get -5y.
-1-5y=7y+11-\left(3y-6\right)
Subtract 6 from 5 to get -1.
-1-5y=7y+11-3y-\left(-6\right)
To find the opposite of 3y-6, find the opposite of each term.
-1-5y=7y+11-3y+6
The opposite of -6 is 6.
-1-5y=4y+11+6
Combine 7y and -3y to get 4y.
-1-5y=4y+17
Add 11 and 6 to get 17.
-1-5y-4y=17
Subtract 4y from both sides.
-1-9y=17
Combine -5y and -4y to get -9y.
-9y=17+1
Add 1 to both sides.
-9y=18
Add 17 and 1 to get 18.
y=\frac{18}{-9}
Divide both sides by -9.
y=-2
Divide 18 by -9 to get -2.
