Solve -2y+x-1=0

$$- 2 y + x - 1 = 0$$

Solve for x

$$x=2y+1$$

Solution Steps

Add 2y to both sides. Anything plus zero gives itself.

$$x-1=2y$$

Add 1 to both sides.

$$x=2y+1$$

Solve for y

$$y=\frac{x-1}{2}$$

Steps for Solving Linear Equation

Subtract x from both sides. Anything subtracted from zero gives its negation.

$$-2y-1=-x$$

Add 1 to both sides.

$$-2y=-x+1$$

The equation is in standard form.

$$-2y=1-x$$

Divide both sides by -2.

$$\frac{-2y}{-2}=\frac{1-x}{-2}$$

Dividing by -2 undoes the multiplication by -2.

$$y=\frac{1-x}{-2}$$

Divide -x+1 by -2.

$$y=\frac{x-1}{2}$$
