xyx=\left(x+1\right)\times 5
Multiply both sides of the equation by x.
x^{2}y=\left(x+1\right)\times 5
Multiply x and x to get x^{2}.
x^{2}y=5x+5
Use the distributive property to multiply x+1 by 5.
\frac{x^{2}y}{x^{2}}=\frac{5x+5}{x^{2}}
Divide both sides by x^{2}.
y=\frac{5x+5}{x^{2}}
Dividing by x^{2} undoes the multiplication by x^{2}.
y=\frac{5\left(x+1\right)}{x^{2}}
Divide 5+5x by x^{2}.
