2x-2+3y-3x=2y+1
Subtract 3x from both sides.
-x-2+3y=2y+1
Combine 2x and -3x to get -x.
-x+3y=2y+1+2
Add 2 to both sides.
-x+3y=2y+3
Add 1 and 2 to get 3.
-x=2y+3-3y
Subtract 3y from both sides.
-x=-y+3
Combine 2y and -3y to get -y.
-x=3-y
The equation is in standard form.
\frac{-x}{-1}=\frac{3-y}{-1}
Divide both sides by -1.
x=\frac{3-y}{-1}
Dividing by -1 undoes the multiplication by -1.
x=y-3
Divide -y+3 by -1.
2x-2+3y-2y=1+3x
Subtract 2y from both sides.
2x-2+y=1+3x
Combine 3y and -2y to get y.
-2+y=1+3x-2x
Subtract 2x from both sides.
-2+y=1+x
Combine 3x and -2x to get x.
y=1+x+2
Add 2 to both sides.
y=3+x
Add 1 and 2 to get 3.
