Consider the absolute value equation:
|x| + |x-2| +|x-4|= 6
How to find the solution(s)?
For |x|, we got x, for x>=0 and -x, for x <0
For |x-2|, we got x-2, for x >= 0 and -(x-2), for x<0
For |x-4|, we got x-4, for x>=0 and -(x-4), for x<0
After this, I'm confused how to find the solutions? is it any easy way to find the solution?
