  1. 2 | x | = 210

    | x | = 105

    x = 105 , x = - 105


  2. lxl means absolute value of x, which can be + or -

    then:

    5lxl - 3lxl = 200 + 10

    2lxl = 210

    lxl = 105

    x= +105 or x= -105

  3. 5x-10=3x+200

    2x=210

    x=105

  4. 5|x| - 3|x| = 210

    2|x| = 210

    |x| = 105

    x = -105 or x = 105

    Take care,
