\left(x-2\right)\left(y+1\right)-y\left(x+3\right)=1
Variable x cannot be equal to 2 since division by zero is not defined. Multiply both sides of the equation by y\left(x-2\right), the least common multiple of y,x-2,xy-2y.
xy+x-2y-2-y\left(x+3\right)=1
Use the distributive property to multiply x-2 by y+1.
xy+x-2y-2-\left(yx+3y\right)=1
Use the distributive property to multiply y by x+3.
xy+x-2y-2-yx-3y=1
To find the opposite of yx+3y, find the opposite of each term.
x-2y-2-3y=1
Combine xy and -yx to get 0.
x-5y-2=1
Combine -2y and -3y to get -5y.
x-2=1+5y
Add 5y to both sides.
x=1+5y+2
Add 2 to both sides.
x=3+5y
Add 1 and 2 to get 3.
x=3+5y\text{, }x\neq 2
Variable x cannot be equal to 2.
\left(x-2\right)\left(y+1\right)-y\left(x+3\right)=1
Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by y\left(x-2\right), the least common multiple of y,x-2,xy-2y.
xy+x-2y-2-y\left(x+3\right)=1
Use the distributive property to multiply x-2 by y+1.
xy+x-2y-2-\left(yx+3y\right)=1
Use the distributive property to multiply y by x+3.
xy+x-2y-2-yx-3y=1
To find the opposite of yx+3y, find the opposite of each term.
x-2y-2-3y=1
Combine xy and -yx to get 0.
x-5y-2=1
Combine -2y and -3y to get -5y.
-5y-2=1-x
Subtract x from both sides.
-5y=1-x+2
Add 2 to both sides.
-5y=3-x
Add 1 and 2 to get 3.
\frac{-5y}{-5}=\frac{3-x}{-5}
Divide both sides by -5.
y=\frac{3-x}{-5}
Dividing by -5 undoes the multiplication by -5.
y=\frac{x-3}{5}
Divide 3-x by -5.
y=\frac{x-3}{5}\text{, }y\neq 0
Variable y cannot be equal to 0.
