2 Jawaban

  • a

    4 + p < 14
    p < 14 - 4
    p < 10

    HP = { 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 }

    b

    11x + 2 < 2x + 39 + 2x + 2
    11x - 2x - 2 x < 39 + 2 - 2
    7x < 39
    x < 39/7

    HP = { x < 39/7 }
  • a][
    4 + p < 14
    p < 14 - 4
    p < 10

    A = {1, 2, 3, 4, 5, 6, 7, 8, 9}

    b][
    11x + 2 < 2x + 39 + 2(x + 1)
    11x + 2 < 2x + 39 + 2x + 2
    11x + 2 < 4x + 41
    11x - 4x < 41 - 2
    7x < 39
    x < 39/7
