11-y-y-5-y=0
Add 5 and 6 to get 11.
11-2y-5-y=0
Combine -y and -y to get -2y.
6-2y-y=0
Subtract 5 from 11 to get 6.
6-3y=0
Combine -2y and -y to get -3y.
-3y=-6
Subtract 6 from both sides. Anything subtracted from zero gives its negation.
y=\frac{-6}{-3}
Divide both sides by -3.
y=2
Divide -6 by -3 to get 2.
