Answer:

x = -3

Step-by-step explanation:

Given the equation,  -4(10 + 3x) - (x + 8) = - 9:

Distribute -4 into (10x + 3x), and - 1 into (x + 8):

-4(10 + 3x) - (x + 8) = - 9

-40 -12x - x - 8 = -9

Combine like terms:

-48 - 13x = -9

Add 48 to both sides:

-48 + 48 - 13x = -9 + 48

-13x = 39

Divide both sides by -13:

\frac{-13x}{-13} = \frac{39}{-13}

x = -3

Therefore, x = -3
