-2x-10=8

-2x=8+10

X= -18/2

hence X= -9

Answer 2

Answer:

Step-by-step explanation:

First, |x| = x when x >= 0 and |-x| = x when x < 0.

So,there are two ways to solve this equation -2|x + 5| = 8.

In the 1st case, let's assume (x + 5) >= 0

=> |x + 5| = x + 5

=> -2(x + 5) = 8

=> x + 5 = 8 / -2 = -4

=> x = -4 - 5 = -9

In the 2nd case, let's assume (x + 5) < 0

=> |x + 5| = -(x + 5) = -x - 5

=> -2 (-x -5) = 8

=> (-x -5) = -4

=> -x = 1

=> x = -1

These are the 2 solutions by solving the math in two different ways.

I hope this helps.

Let me if you have any more questions.
