xy+3\left(x+2\right)+2\left(x+1\right)\left(-3\right)=0
Multiply both sides of the equation by 2\left(x+1\right).
xy+3x+6+2\left(x+1\right)\left(-3\right)=0
Use the distributive property to multiply 3 by x+2.
xy+3x+6-6\left(x+1\right)=0
Multiply 2 and -3 to get -6.
xy+3x+6-6x-6=0
Use the distributive property to multiply -6 by x+1.
xy-3x+6-6=0
Combine 3x and -6x to get -3x.
xy-3x=0
Subtract 6 from 6 to get 0.
xy=3x
Add 3x to both sides. Anything plus zero gives itself.
\frac{xy}{x}=\frac{3x}{x}
Divide both sides by x.
y=\frac{3x}{x}
Dividing by x undoes the multiplication by x.
y=3
Divide 3x by x.
xy+3\left(x+2\right)+2\left(x+1\right)\left(-3\right)=0
Variable x cannot be equal to -1 since division by zero is not defined. Multiply both sides of the equation by 2\left(x+1\right).
xy+3x+6+2\left(x+1\right)\left(-3\right)=0
Use the distributive property to multiply 3 by x+2.
xy+3x+6-6\left(x+1\right)=0
Multiply 2 and -3 to get -6.
xy+3x+6-6x-6=0
Use the distributive property to multiply -6 by x+1.
xy-3x+6-6=0
Combine 3x and -6x to get -3x.
xy-3x=0
Subtract 6 from 6 to get 0.
\left(y-3\right)x=0
Combine all terms containing x.
x=0
Divide 0 by -3+y.
xy+3\left(x+2\right)+2\left(x+1\right)\left(-3\right)=0
Multiply both sides of the equation by 2\left(x+1\right).
xy+3x+6+2\left(x+1\right)\left(-3\right)=0
Use the distributive property to multiply 3 by x+2.
xy+3x+6-6\left(x+1\right)=0
Multiply 2 and -3 to get -6.
xy+3x+6-6x-6=0
Use the distributive property to multiply -6 by x+1.
xy-3x+6-6=0
Combine 3x and -6x to get -3x.
xy-3x=0
Subtract 6 from 6 to get 0.
xy=3x
Add 3x to both sides. Anything plus zero gives itself.
\frac{xy}{x}=\frac{3x}{x}
Divide both sides by x.
y=\frac{3x}{x}
Dividing by x undoes the multiplication by x.
y=3
Divide 3x by x.
