  1. We have to find the number of solutions of the equation ||2x – 3| – m| = m where m > 0.

    solution : here m > 0 , it means ||2x – 3| – m| is positive term.

    so, |2x – 3| – m = m

    ⇒|2x – 3| = 2m

    ⇒2x – 3 = ± 2m

    ⇒2x = 3 ± 2m

    ⇒x = (3 ± 2m)/2

    also |2x – 3| = 0 ⇒2x = 3 ⇒x = 3/2

    Therefore x = (3 + 2m)/2, (3 – 2m)/2 and 3/2 are the solutions of equation.

    so there are three solutions of the given equation.
