Add 12 to both sides
2|n| = 16 + 12
Simplify 16 + 12 to 28
2|n| = 28
Divide both sides by 2
|n| = 28/2
Simplify 28/2 to 14
|n| = 14
Break down the problem into these 2 equations
n = 14
-n = 14
Solve the 1st equation: n = 14
n = 14
Solve the 2nd equation: -n = 14
n = -14
When you collect all solutions;
n = ±14
