Question

$$-18-5(9-x)=8$$

Solve for x

$x = \frac{71}{5} = 14\frac{1}{5} = 14.2$

Steps for Solving Linear Equation

Use the distributive property to multiply $-5$ by $9-x$.

$$-18-45+5x=8$$

Subtract $45$ from $-18$ to get $-63$.

$$-63+5x=8$$

Add $63$ to both sides.

$$5x=8+63$$

Add $8$ and $63$ to get $71$.

$$5x=71$$

Divide both sides by $5$.

$$x=\frac{71}{5}$$
