Hi there!

»»————- ★ ————-««

I believe your answer is:


\huge x=-6

»»————- ★ ————-««

Here’s why:

⸻⸻⸻⸻


\boxed{\text{Solving for 'x'...}}\\\\-8x-4(x-4)=88\\-------------\\\rightarrow -8x-4x+16=88\\\\\rightarrow -12x + 16 = 88\\\\\rightarrow -12x + 16 - 16 = 88 - 16\\\\\rightarrow -12x = 72\\\\\rightarrow (-12x=72)/(12)\\\\\rightarrow \boxed{x=-6}

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Answer: x = -6

Step-by-step explanation: Start by changing the - 4 to plus a negative 4 so that you know you're distributing a -4 through the parentheses.

So we have -8x - 4x + 16 = 88.

Simplifying the left side further gives us -12x + 16 = 88.

Now subtract 16 from both sides to get -12x = 72.

From here it should be easy to find the x = -6.
