|x - 3| + |2x - 8| = 10

2 Jawaban

  • l x-3 l + l 2x - 8 l = 10
    x-3 + 2x-8 = 10
    3x-11 = 10
    3x = 21
    x = 21 / 3 = 7
    jadi, x=7     , lx-3l = 4   ,   l2x-8 l = 6

  • |x - 3| + |2x - 8| = 10
    x - 3 + 2x - 8 = 10
    3x - 11 = 10
    x = (10 + 11)/3
    x = 7

    3x - 11 = -10
    x = (-10 + 11)/3
    x = 1/3

    HP = {1/3 , 7}
