  • Bab : Persamaan Linear Satu Variebel
    Kelas : VII SMP

    1 + 9x = 28
    9x = 28 - 1
    9x = 27
    x = 3


    6x - 5 = 25
    6x = 25 + 5
    6x = 30
    x = 5


    9 - 6x = 3
    -6x = 3 - 9
    -6x = -6
    x = 1


    3x + 3 = 27
    3x = 27 - 3
    3x = 24
    x = 8

    1] 1 + 9x = 28
    9x = 28 - 1
    x = 27/9
    x = 3

    2] 6x - 5 = 25
    6x = 25 + 5
    x = 30/6
    x = 5

    3] 9 - 6x = 3
    6x = 9 - 3
    x = 6/6
    x = 1

    4] 3x + 3 = 27
    3x = 27 - 3
    x = 24/3
    x = 8
