77+y=186+11-2y
Subtract 35 from 221 to get 186.
77+y=197-2y
Add 186 and 11 to get 197.
77+y+2y=197
Add 2y to both sides.
77+3y=197
Combine y and 2y to get 3y.
3y=197-77
Subtract 77 from both sides.
3y=120
Subtract 77 from 197 to get 120.
y=\frac{120}{3}
Divide both sides by 3.
y=40
Divide 120 by 3 to get 40.
