To solve the equation -4x - 3(-4x - 23) = 13, we can simplify and then solve for x using the following steps:

-4x - 3(-4x - 23) = 13

First, distribute the -3 to the terms inside the parentheses:

-4x + 12x + 69 = 13

Combine like terms:

-4x + 12x + 69 = 13

(12x - 4x) + 69 = 13

8x + 69 = 13

Next, isolate the variable x by subtracting 69 from both sides:

8x + 69 - 69 = 13 - 69

8x = -56

Finally, solve for x by dividing both sides of the equation by 8:

8x/8 = -56/8

x = -7

Therefore, the solution to the equation -4x - 3(-4x - 23) = 13 is x = -7.
