Question

solve for w|w|=4if there is more than one solution, seperate them with commas. If there is no solution, type "there is no solution"w=?

Answer 1

$w\text{ = -4, 4}$

Here is an absolute value equation we are to solve

The barrier around w shows that it could take a positive or negative value

This is because the absolute value barrier will make anything that goes into it turn positive

Mathematically, we have the value of w as;

$w\text{ = -4,4}$

The reason for having the negative value is because if -4 was to go into the barrier, then it would have turned out positive
