2x-2y+1=0M
Multiply 0 and 1 to get 0.
2x-2y+1=0
Anything times zero gives zero.
2x+1=2y
Add 2y to both sides. Anything plus zero gives itself.
2x=2y-1
Subtract 1 from both sides.
\frac{2x}{2}=\frac{2y-1}{2}
Divide both sides by 2.
x=\frac{2y-1}{2}
Dividing by 2 undoes the multiplication by 2.
x=y-\frac{1}{2}
Divide 2y-1 by 2.
