Question

$$-8+8x=-5+3(3x+4)$$

Solve for x

$x=-15$

Steps for Solving Linear Equation

Use the distributive property to multiply $3$ by $3x+4$.

$$-8+8x=-5+9x+12$$

Add $-5$ and $12$ to get $7$.

$$-8+8x=7+9x$$

Subtract $9x$ from both sides.

$$-8+8x-9x=7$$

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

$$-8-x=7$$

Add $8$ to both sides.

$$-x=7+8$$

Add $7$ and $8$ to get $15$.

$$-x=15$$

Multiply both sides by $-1$.

$$x=-15$$
