Solve x+x2=9x

$$x+x2 = 9x$$

Solve for x

$$x=\frac{x_{2}}{8}$$

Steps for Solving Linear Equation

Subtract 9x from both sides.

$$x+x_{2}-9x=0$$

Combine x and -9x to get -8x.

$$-8x+x_{2}=0$$

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

$$-8x=-x_{2}$$

Divide both sides by -8.

$$\frac{-8x}{-8}=-\frac{x_{2}}{-8}$$

Dividing by -8 undoes the multiplication by -8.

$$x=-\frac{x_{2}}{-8}$$

Divide -x_{2} by -8.

$$x=\frac{x_{2}}{8}$$

Solve for x_2

$$x_{2}=8x$$

Solution Steps

Subtract x from both sides.

$$x_{2}=9x-x$$

Combine 9x and -x to get 8x.

$$x_{2}=8x$$
