3\left(2x-2\right)\times \frac{3\left(y+1\right)}{2}=-20
Multiply both sides of the equation by 2.
\left(6x-6\right)\times \frac{3\left(y+1\right)}{2}=-20
Use the distributive property to multiply 3 by 2x-2.
\left(6x-6\right)\times \frac{3y+3}{2}=-20
Use the distributive property to multiply 3 by y+1.
\frac{\left(6x-6\right)\left(3y+3\right)}{2}=-20
Express \left(6x-6\right)\times \frac{3y+3}{2} as a single fraction.
\frac{18xy+18x-18y-18}{2}=-20
Use the distributive property to multiply 6x-6 by 3y+3.
18xy+18x-18y-18=-20\times 2
Multiply both sides by 2.
18xy+18x-18y-18=-40
Multiply -20 and 2 to get -40.
18xy+18x-18=-40+18y
Add 18y to both sides.
18xy+18x=-40+18y+18
Add 18 to both sides.
18xy+18x=-22+18y
Add -40 and 18 to get -22.
\left(18y+18\right)x=-22+18y
Combine all terms containing x.
\left(18y+18\right)x=18y-22
The equation is in standard form.
\frac{\left(18y+18\right)x}{18y+18}=\frac{18y-22}{18y+18}
Divide both sides by 18y+18.
x=\frac{18y-22}{18y+18}
Dividing by 18y+18 undoes the multiplication by 18y+18.
x=\frac{9y-11}{9\left(y+1\right)}
Divide -22+18y by 18y+18.
3\left(2x-2\right)\times \frac{3\left(y+1\right)}{2}=-20
Multiply both sides of the equation by 2.
\left(6x-6\right)\times \frac{3\left(y+1\right)}{2}=-20
Use the distributive property to multiply 3 by 2x-2.
\left(6x-6\right)\times \frac{3y+3}{2}=-20
Use the distributive property to multiply 3 by y+1.
\frac{\left(6x-6\right)\left(3y+3\right)}{2}=-20
Express \left(6x-6\right)\times \frac{3y+3}{2} as a single fraction.
\frac{18xy+18x-18y-18}{2}=-20
Use the distributive property to multiply 6x-6 by 3y+3.
18xy+18x-18y-18=-20\times 2
Multiply both sides by 2.
18xy+18x-18y-18=-40
Multiply -20 and 2 to get -40.
18xy-18y-18=-40-18x
Subtract 18x from both sides.
18xy-18y=-40-18x+18
Add 18 to both sides.
18xy-18y=-22-18x
Add -40 and 18 to get -22.
\left(18x-18\right)y=-22-18x
Combine all terms containing y.
\left(18x-18\right)y=-18x-22
The equation is in standard form.
\frac{\left(18x-18\right)y}{18x-18}=\frac{-18x-22}{18x-18}
Divide both sides by 18x-18.
y=\frac{-18x-22}{18x-18}
Dividing by 18x-18 undoes the multiplication by 18x-18.
y=-\frac{9x+11}{9\left(x-1\right)}
Divide -22-18x by 18x-18.
