Answer: x=2/3
Step-by-step explanation:
So our two equations are y=-8x-4 and y=-16, and since in both equations, something equals the same y, those two are the same. So we can combine the two into -16=-8x-4. In the question, they are asking to solve for x. So to do that, you need to isolate your variable. Now for solving algebraic equations, you use reverse PEMDAS (SADMEP), meaning you add 4 to both sides to clear the -4 one the rights side to get -12=-8x. Then you divide both sides by -8 to get 12/8, which simplifies to 3/2.

I believe your answer is:
"Add 4 to both sides, and then divide by 2. The solution is x = 12."

Here’s why:
⸻⸻⸻⸻
- To solve for 'x', we would have to use inverse operations.
- We would first have to add four to both sides to undo the negative four. Addition is the opposite of subtraction.
- We would then divide by 2 to isolate 'x'. Division is the opposite of multiplication.
