8=5x-yx
Use the distributive property to multiply 5-y by x.
5x-yx=8
Swap sides so that all variable terms are on the left hand side.
\left(5-y\right)x=8
Combine all terms containing x.
\frac{\left(5-y\right)x}{5-y}=\frac{8}{5-y}
Divide both sides by 5-y.
x=\frac{8}{5-y}
Dividing by 5-y undoes the multiplication by 5-y.
8=5x-yx
Use the distributive property to multiply 5-y by x.
5x-yx=8
Swap sides so that all variable terms are on the left hand side.
-yx=8-5x
Subtract 5x from both sides.
\left(-x\right)y=8-5x
The equation is in standard form.
\frac{\left(-x\right)y}{-x}=\frac{8-5x}{-x}
Divide both sides by -x.
y=\frac{8-5x}{-x}
Dividing by -x undoes the multiplication by -x.
y=5-\frac{8}{x}
Divide 8-5x by -x.
