  • 1 |x - 3| + 5 = 2
    |x - 3| = 2 - 5
    x - 3 = -3
    x = -3 + 3
    x = 0
    x - 3 = 3
    x = 3 + 3
    x = 6
    HP = {0, 6}
    2 2|x - 3| + 4 = 6
    2|x - 3| = 6 - 4
    2|x - 3| = 2
    |x - 3| = 2/2
    x = 2/2 + 3
    x = 2/2 + 6/6
    x = 3/6 + 6/6
    x = 9/6
    |x - 3| = -2/2
    x = -2/2 + 3
    x = -2/2 + 6/6
    x = -3/6 + 6/6
    x = 3/6
    HP = {3/6, 9/6}
