4x-5+9y-x=-3
Subtract x from both sides.
3x-5+9y=-3
Combine 4x and -x to get 3x.
3x+9y=-3+5
Add 5 to both sides.
3x+9y=2
Add -3 and 5 to get 2.
3x=2-9y
Subtract 9y from both sides.
\frac{3x}{3}=\frac{2-9y}{3}
Divide both sides by 3.
x=\frac{2-9y}{3}
Dividing by 3 undoes the multiplication by 3.
x=\frac{2}{3}-3y
Divide 2-9y by 3.
-5+9y=x-3-4x
Subtract 4x from both sides.
-5+9y=-3x-3
Combine x and -4x to get -3x.
9y=-3x-3+5
Add 5 to both sides.
9y=-3x+2
Add -3 and 5 to get 2.
9y=2-3x
The equation is in standard form.
\frac{9y}{9}=\frac{2-3x}{9}
Divide both sides by 9.
y=\frac{2-3x}{9}
Dividing by 9 undoes the multiplication by 9.
y=-\frac{x}{3}+\frac{2}{9}
Divide -3x+2 by 9.
