9x=7-16y
Subtract 16y from both sides.
\frac{9x}{9}=\frac{7-16y}{9}
Divide both sides by 9.
x=\frac{7-16y}{9}
Dividing by 9 undoes the multiplication by 9.
16y=7-9x
Subtract 9x from both sides.
\frac{16y}{16}=\frac{7-9x}{16}
Divide both sides by 16.
y=\frac{7-9x}{16}
Dividing by 16 undoes the multiplication by 16.
