Question

$$x-8x+K=0$$

Solve for K

$K=7x$

Show Solution

Solve for x

$x=\frac{K}{7}$

Steps for Solving Linear Equation

Combine $x$ and $-8x$ to get $-7x$.

$$-7x+K=0$$

Subtract $K$ from both sides. Anything subtracted from zero gives its negation.

$$-7x=-K$$

Divide both sides by $-7$.

$$\frac{-7x}{-7}=-\frac{K}{-7}$$

Dividing by $-7$ undoes the multiplication by $-7$.

$$x=-\frac{K}{-7}$$

Divide $-K$ by $-7$.

$$x=\frac{K}{7}$$
