2 Jawaban

  • |3x-8| = 5
    3x =5+8
    x =13 : 3
    x = 13/3

    -|3x-8|=5
    -3x+8=5
    -3x= 5-8
    -3x = -3
    x = -3 : -3
    x = 1
    Hp ={13/3 , 1}
  • |3x-8| = 5
    3x-8 = 5
    3x = 5 + 8
    3x = 13
    x = 13/3
    x = 4⅓

    |3x-8| = -5
    3x-8 = -5
    3x = -5 + 8
    3x = 3
    x = 3/3
    x = 1

    HP = {4⅓(13/3) & 1}
