22x+y-2x=13
Subtract 2x from both sides.
20x+y=13
Combine 22x and -2x to get 20x.
20x=13-y
Subtract y from both sides.
\frac{20x}{20}=\frac{13-y}{20}
Divide both sides by 20.
x=\frac{13-y}{20}
Dividing by 20 undoes the multiplication by 20.
y=2x+13-22x
Subtract 22x from both sides.
y=-20x+13
Combine 2x and -22x to get -20x.
