4x+2y-3x=1
Subtract 3x from both sides.
x+2y=1
Combine 4x and -3x to get x.
x=1-2y
Subtract 2y from both sides.
2y=3x+1-4x
Subtract 4x from both sides.
2y=-x+1
Combine 3x and -4x to get -x.
2y=1-x
The equation is in standard form.
\frac{2y}{2}=\frac{1-x}{2}
Divide both sides by 2.
y=\frac{1-x}{2}
Dividing by 2 undoes the multiplication by 2.
