Answer: X = -8
Explanation:
To solve the equation 10x + 80 = 0 for x, you'll need to isolate x on one side of the equation. Here are the steps to do that:
Subtract 80 from both sides of the equation:
10x + 80 - 80 = 0 - 80
This simplifies to:
10x = -80
Now, to isolate x, divide both sides by 10:
(10x)/10 = (-80)/10
This simplifies to:
x = -8
So, the solution to the equation 10x + 80 = 0 is:
x = -8
