3x+6=-3(2x+4)<br><br><br> Show your work

Lera25 [3.4K]

Answer:

$\boxed {x = -2}$

Step-by-step explanation:

Solve for the value of $x$ :

$3x + 6 = -3(2x + 4)$

-Use <u>Distributive Property</u>:

$3x + 6 = -3(2x + 4)$

$3x + 6 = -6x - 12$

-Take $6x$ and add it to $3x$ :

$3x + 6 + 6x = -6x + 6x - 12$

$9x + 6 = -12$

-Subtract both sides by $6$ :

$9x + 6 - 6 = -12 - 6$

$9x = -18$

-Divide both sides by $9$ :

$\frac{9x}{9} = \frac{-18}{9}$

$\boxed {x = -2}$

Therefore, the value of $x$ is $-2$ .
