3\left(3-y\right)+4\left(2y-2\right)=2\left(2y+1\right)
Multiply both sides of the equation by 12, the least common multiple of 4,3,6.
9-3y+4\left(2y-2\right)=2\left(2y+1\right)
Use the distributive property to multiply 3 by 3-y.
9-3y+8y-8=2\left(2y+1\right)
Use the distributive property to multiply 4 by 2y-2.
9+5y-8=2\left(2y+1\right)
Combine -3y and 8y to get 5y.
1+5y=2\left(2y+1\right)
Subtract 8 from 9 to get 1.
1+5y=4y+2
Use the distributive property to multiply 2 by 2y+1.
1+5y-4y=2
Subtract 4y from both sides.
1+y=2
Combine 5y and -4y to get y.
y=2-1
Subtract 1 from both sides.
y=1
Subtract 1 from 2 to get 1.
