13x=90-16y
Subtract 16y from both sides.
\frac{13x}{13}=\frac{90-16y}{13}
Divide both sides by 13.
x=\frac{90-16y}{13}
Dividing by 13 undoes the multiplication by 13.
16y=90-13x
Subtract 13x from both sides.
\frac{16y}{16}=\frac{90-13x}{16}
Divide both sides by 16.
y=\frac{90-13x}{16}
Dividing by 16 undoes the multiplication by 16.
y=-\frac{13x}{16}+\frac{45}{8}
Divide 90-13x by 16.
