Q.5
We must be careful because an absolute value gives two values. We must separate into two possibilities, where the absolute is positive, 0 or negative.
1. x≥3 (Where both are positive)
→ x-1+x-3=6 → 2x-4=6 → x=5 is the solution.
2. 1≤x<3 (Where x-1≥0, x-3<0)
→ x-1-x+3=6 → 2=6 is falsehood. → There is no solution.
3. x<1 (Where both are negative)
→ -x+1-x+3=6 → -2x+4=6 → x=-1 is the solution.
Q.5 All the solutions are x=5 or x=-1.
Q.6
If the absolute value of a number is one, what is the number? It should be either 1 or -1. → ||x-1|-1| is either 0 or 2.(Two cases)
1. Where ||x-1|-1|=0
→ |x-1|-1=0 → |x-1|=1 → x=2 or x=0
2. Where ||x-1|-1|=2
→ |x-1|-1=±2 → |x-1| should be 3 because the absolute value is not negative.
→ x=4
