-2\left(5-3y\right)=11-y
Multiply both sides of the equation by 4, the least common multiple of 2,4.
-10+6y=11-y
Use the distributive property to multiply -2 by 5-3y.
-10+6y+y=11
Add y to both sides.
-10+7y=11
Combine 6y and y to get 7y.
7y=11+10
Add 10 to both sides.
7y=21
Add 11 and 10 to get 21.
y=\frac{21}{7}
Divide both sides by 7.
y=3
Divide 21 by 7 to get 3.
