18x=-90-15y
Subtract 15y from both sides.
18x=-15y-90
The equation is in standard form.
\frac{18x}{18}=\frac{-15y-90}{18}
Divide both sides by 18.
x=\frac{-15y-90}{18}
Dividing by 18 undoes the multiplication by 18.
x=-\frac{5y}{6}-5
Divide -90-15y by 18.
15y=-90-18x
Subtract 18x from both sides.
15y=-18x-90
The equation is in standard form.
\frac{15y}{15}=\frac{-18x-90}{15}
Divide both sides by 15.
y=\frac{-18x-90}{15}
Dividing by 15 undoes the multiplication by 15.
y=-\frac{6x}{5}-6
Divide -90-18x by 15.
