4\left(4y-11\right)+3\left(13-7y\right)=120
Multiply both sides of the equation by 60, the least common multiple of 15,20.
16y-44+3\left(13-7y\right)=120
Use the distributive property to multiply 4 by 4y-11.
16y-44+39-21y=120
Use the distributive property to multiply 3 by 13-7y.
16y-5-21y=120
Add -44 and 39 to get -5.
-5y-5=120
Combine 16y and -21y to get -5y.
-5y=120+5
Add 5 to both sides.
-5y=125
Add 120 and 5 to get 125.
y=\frac{125}{-5}
Divide both sides by -5.
y=-25
Divide 125 by -5 to get -25.
