11x=90-2y
Subtract 2y from both sides.
\frac{11x}{11}=\frac{90-2y}{11}
Divide both sides by 11.
x=\frac{90-2y}{11}
Dividing by 11 undoes the multiplication by 11.
2y=90-11x
Subtract 11x from both sides.
\frac{2y}{2}=\frac{90-11x}{2}
Divide both sides by 2.
y=\frac{90-11x}{2}
Dividing by 2 undoes the multiplication by 2.
y=-\frac{11x}{2}+45
Divide 90-11x by 2.
