8x=127-9y
Subtract 9y from both sides.
\frac{8x}{8}=\frac{127-9y}{8}
Divide both sides by 8.
x=\frac{127-9y}{8}
Dividing by 8 undoes the multiplication by 8.
9y=127-8x
Subtract 8x from both sides.
\frac{9y}{9}=\frac{127-8x}{9}
Divide both sides by 9.
y=\frac{127-8x}{9}
Dividing by 9 undoes the multiplication by 9.
