  1. x-5y
    -4.28 -5(-4.68) =
    -4.28 + 23.40 = +19.12
    Now you round to the nearest tenth.

  2. well 5 y = 23.4
    so
    x - 5 y = -4.28 - (-23.4)
    minus a minus is a plus
    so
    x - 5 y = -4.28 + 23.4
    = 19.12 which to the nearest tenth is 19.1

  3. well 5 y = -23.4 forgot minus sign
    so
    x - 5 y = -4.28 - (-23.4)
    minus a minus is a plus
    so
    x - 5 y = -4.28 + 23.4
    = 19.12 which to the nearest tenth is 19.1
