Solve y=x2-x+12

$$y = x 2 - x + 12$$

Solve for x

$$x=x_{2}-y+12$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$x_{2}-x+12=y$$

Subtract x_{2} from both sides.

$$-x+12=y-x_{2}$$

Subtract 12 from both sides.

$$-x=y-x_{2}-12$$

The equation is in standard form.

$$-x=-x_{2}+y-12$$

Divide both sides by -1.

$$\frac{-x}{-1}=\frac{-x_{2}+y-12}{-1}$$

Dividing by -1 undoes the multiplication by -1.

$$x=\frac{-x_{2}+y-12}{-1}$$

Divide y-x_{2}-12 by -1.

$$x=x_{2}-y+12$$

Solve for x_2

$$x_{2}=x+y-12$$

Solution Steps

Swap sides so that all variable terms are on the left hand side.

$$x_{2}-x+12=y$$

Add x to both sides.

$$x_{2}+12=y+x$$

Subtract 12 from both sides.

$$x_{2}=y+x-12$$
