Question

Rewrite in standard form |x|-4=0

Answer 1

x = ±4

Explanation:

we are given |x|-4=0

The first step is to add 4 on both sides of the equation;

|x|-4+4=0+4

|x|=4

Getting rid of the absolute symbol implies we have to add the positive and negative symbols to the right hand side of the equation;

x = ±4
