Answer 1

@pillspotion Nothing will change until you learn how the absolute value works.

I forget how this works..

Answer 3

15 + | -3 | - 4 --- absolute values are positive
15 + 3 - 4
now you do the math

Answer 4

You got 2 equations, right?

Answer 5

The absolute value removes the negative sign if there is one, otherwise it does nothing.

Answer 6

15 - 3 - 4

and

15 + 3 - 4

?

You solve them both?

Oh..so that's all it does?

@iGreen You only do that for something like: \[
|x-3|=5
\]

Answer 9

Oh..

Answer 10

I don't know how to solve that either..

Answer 11

Forgot about the absolute value things..

Answer 12

You solve \[
