The answer to the problem is n=6 and n=1

Explanation:

With absolute value, you'll have two answers; one of them assuming 2n5 is positive and one assuming 2n5 is negative.

Therefore, we have to set it up like this:

2n5=7

2n5=7

We set it up like this because |7| and |7| both equal 7.

We can solve both equations pretty easily:

2n5=7
2n=12
n=6

2n5=7
2n=2
n=1
