yx=-18-9y
Subtract 9y from both sides.
yx=-9y-18
The equation is in standard form.
\frac{yx}{y}=\frac{-9y-18}{y}
Divide both sides by y.
x=\frac{-9y-18}{y}
Dividing by y undoes the multiplication by y.
x=-9-\frac{18}{y}
Divide -18-9y by y.
\left(x+9\right)y=-18
Combine all terms containing y.
\frac{\left(x+9\right)y}{x+9}=-\frac{18}{x+9}
Divide both sides by x+9.
y=-\frac{18}{x+9}
Dividing by x+9 undoes the multiplication by x+9.
