2x-1=-2y
Subtract 2y from both sides. Anything subtracted from zero gives its negation.
2x=-2y+1
Add 1 to both sides.
2x=1-2y
The equation is in standard form.
\frac{2x}{2}=\frac{1-2y}{2}
Divide both sides by 2.
x=\frac{1-2y}{2}
Dividing by 2 undoes the multiplication by 2.
x=\frac{1}{2}-y
Divide -2y+1 by 2.
2y-1=-2x
Subtract 2x from both sides. Anything subtracted from zero gives its negation.
2y=-2x+1
Add 1 to both sides.
2y=1-2x
The equation is in standard form.
\frac{2y}{2}=\frac{1-2x}{2}
Divide both sides by 2.
y=\frac{1-2x}{2}
Dividing by 2 undoes the multiplication by 2.
y=\frac{1}{2}-x
Divide -2x+1 by 2.
