10x=90-15y
Subtract 15y from both sides.
\frac{10x}{10}=\frac{90-15y}{10}
Divide both sides by 10.
x=\frac{90-15y}{10}
Dividing by 10 undoes the multiplication by 10.
x=-\frac{3y}{2}+9
Divide 90-15y by 10.
15y=90-10x
Subtract 10x from both sides.
\frac{15y}{15}=\frac{90-10x}{15}
Divide both sides by 15.
y=\frac{90-10x}{15}
Dividing by 15 undoes the multiplication by 15.
y=-\frac{2x}{3}+6
Divide 90-10x by 15.
