Answer
n=13 and n=-33
Work Step by Step
To solve, first isolate n. Subtract 10 from both sides of the equation. You end up with the first answer n=13. The next answer can be found by making the 23 negative. We do this because we are solving for absolute value. The new equation becomes n+10=-23. Isolate n in this equation. Subtract 10 from both sides. The second answer is n=-33.
To check, substitute each solution into x.
$\mid$$13+10$$\mid$$=23$
$\mid$$-33+10$$\mid$$=23$
