-6x=90-15y
Subtract 15y from both sides.
\frac{-6x}{-6}=\frac{90-15y}{-6}
Divide both sides by -6.
x=\frac{90-15y}{-6}
Dividing by -6 undoes the multiplication by -6.
x=\frac{5y}{2}-15
Divide 90-15y by -6.
15y=90+6x
Add 6x to both sides.
15y=6x+90
The equation is in standard form.
\frac{15y}{15}=\frac{6x+90}{15}
Divide both sides by 15.
y=\frac{6x+90}{15}
Dividing by 15 undoes the multiplication by 15.
y=\frac{2x}{5}+6
Divide 90+6x by 15.
