Solve y2-2x+1=0

$$y2-2x+1=0$$

Solve for x

$$x=\frac{y_{2}+1}{2}$$

Steps for Solving Linear Equation

Subtract y_{2} from both sides. Anything subtracted from zero gives its negation.

$$-2x+1=-y_{2}$$

Subtract 1 from both sides.

$$-2x=-y_{2}-1$$

Divide both sides by -2.

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

Dividing by -2 undoes the multiplication by -2.

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

Divide -y_{2}-1 by -2.

$$x=\frac{y_{2}+1}{2}$$

Solve for y_2

$$y_{2}=2x-1$$

Solution Steps

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

$$y_{2}+1=2x$$

Subtract 1 from both sides.

$$y_{2}=2x-1$$
