xy-5-x=3
Subtract x from both sides.
xy-x=3+5
Add 5 to both sides.
xy-x=8
Add 3 and 5 to get 8.
\left(y-1\right)x=8
Combine all terms containing x.
\frac{\left(y-1\right)x}{y-1}=\frac{8}{y-1}
Divide both sides by y-1.
x=\frac{8}{y-1}
Dividing by y-1 undoes the multiplication by y-1.
xy=x+3+5
Add 5 to both sides.
xy=x+8
Add 3 and 5 to get 8.
\frac{xy}{x}=\frac{x+8}{x}
Divide both sides by x.
y=\frac{x+8}{x}
Dividing by x undoes the multiplication by x.
