Answer:


\boxed {x = -2}

Explanation:

Solve for the value of
x:


-5x - 4 = 3x + 12

-Take
3x and subtract it from
-5x:


-5x - 4 - 3x = 3x - 3x + 12


-8x - 4 = 12

-Add
4 to both sides:


-8x - 4 + 4 = 12 + 4


-8x = 16

-Divide both sides by
-8:


(-8x)/(-8) = (16)/(-8)


\boxed {x = -2}

Therefore, the value of
x is
-2.
