Answer 2

To solve the equations:

1. • |x| = -8 or -|x| = 12

For the first equation, we have:

-|x| = -8

To isolate the absolute value, we multiply both sides by -1:

|-x| = 8

This means that the absolute value of -x is equal to 8. Since the absolute value of a number is always positive, we can drop the absolute value signs:

-x = 8

Now we solve for x by multiplying both sides by -1:

x = -8

So one solution is x = -8.

For the second equation, we have:

-|x| = 12

Again, we multiply both sides by -1:

|-x| = 12

This means that the absolute value of -x is equal to 12. Dropping the absolute value signs:

-x = 12

Solving for x by multiplying both sides by -1:

x = -12

So another solution is x = -12.

Therefore, the solutions to the equation - |x| = -8, 12 are x = -8 and x = -12.

2. -|-x| = -2 2/3

Let's simplify the equation step by step. We start with:

-|-x| = -2 2/3

Since |-x| is always positive, we can rewrite the equation as:

-1 * |-x| = -2 2/3

Now, we can drop the negative sign on the left side:

|-x| = -2 2/3

However, the absolute value of a number is always non-negative, so there are no solutions for this equation.
