2y-4-3\left(4y-1\right)=9\left(1-y\right)
Use the distributive property to multiply 2 by y-2.
2y-4-12y+3=9\left(1-y\right)
Use the distributive property to multiply -3 by 4y-1.
-10y-4+3=9\left(1-y\right)
Combine 2y and -12y to get -10y.
-10y-1=9\left(1-y\right)
Add -4 and 3 to get -1.
-10y-1=9-9y
Use the distributive property to multiply 9 by 1-y.
-10y-1+9y=9
Add 9y to both sides.
-y-1=9
Combine -10y and 9y to get -y.
-y=9+1
Add 1 to both sides.
-y=10
Add 9 and 1 to get 10.
y=-10
Multiply both sides by -1.
