4-9y-54=5\left(y-1\right)-26y
Use the distributive property to multiply -9 by y+6.
-50-9y=5\left(y-1\right)-26y
Subtract 54 from 4 to get -50.
-50-9y=5y-5-26y
Use the distributive property to multiply 5 by y-1.
-50-9y=-21y-5
Combine 5y and -26y to get -21y.
-50-9y+21y=-5
Add 21y to both sides.
-50+12y=-5
Combine -9y and 21y to get 12y.
12y=-5+50
Add 50 to both sides.
12y=45
Add -5 and 50 to get 45.
y=\frac{45}{12}
Divide both sides by 12.
y=\frac{15}{4}
Reduce the fraction \frac{45}{12} to lowest terms by extracting and canceling out 3.
