tentukan penyelesaian dari a.4m + 5=25 B.5n-4 = 3n + 8 C.3-7k=17 D. 4+6p=19+3p

1 Jawaban

  • 4m + 5 = 25
    4m = 25 - 5
    4m = 20
    m = 20/4 = 5

    5n - 4 = 3n + 8
    5n - 3n = 8 + 4
    2n = 12
    n = 12/2 = 6

    3 - 7k = 17
    -7k = 17 - 3
    -7k = 14
    k = 14/-7 = -2

    4 + 6p = 19 + 3p
    6p - 3p = 19 - 4
    3p = 15
    p = 15/3 = 5
