Solve the absolute value equation? 2|n-4|-20=4

the answer is 2 4n 20

Remeember

if you have

|a|=b then solve for a that satisfiies a=b and a=-b

2|n-4|-20=4

add 20 to both sides

2|n-4|=24

divide both sides by 2

|n-4|=12

solve

n-4=12 and n-4=-12

add 4 to both sides

n=16 and n=-8

n=-8 and 16
