Answer 2

Answer:

$x=-6$

Step-by-step explanation:

$5x+8+3x+4=-40+4$

⇒ Subtract 4 from both sides:

$5x+8+3x+4-4=-40+4-4$

$5x+8+3x=-40$

⇒ Combine like terms:

$5x+3x=8x$

$8x+8=-40$

⇒ Subtract 8 from both sides:

$8x+8-8=-40-8$

$8x=-48$

⇒ Divide both sides by 8:

$\frac{8x}{8}=\frac{-48}{8}$

$x=-6$
