x+5x_{4}=-15
Multiply both sides of the equation by 5.
x=-15-5x_{4}
Subtract 5x_{4} from both sides.
x+5x_{4}=-15
Multiply both sides of the equation by 5.
5x_{4}=-15-x
Subtract x from both sides.
5x_{4}=-x-15
The equation is in standard form.
\frac{5x_{4}}{5}=\frac{-x-15}{5}
Divide both sides by 5.
x_{4}=\frac{-x-15}{5}
Dividing by 5 undoes the multiplication by 5.
x_{4}=-\frac{x}{5}-3
Divide -15-x by 5.
