9x=151-11y
Subtract 11y from both sides.
\frac{9x}{9}=\frac{151-11y}{9}
Divide both sides by 9.
x=\frac{151-11y}{9}
Dividing by 9 undoes the multiplication by 9.
11y=151-9x
Subtract 9x from both sides.
\frac{11y}{11}=\frac{151-9x}{11}
Divide both sides by 11.
y=\frac{151-9x}{11}
Dividing by 11 undoes the multiplication by 11.
