1 . 5x = 25 + 2x 2.2x -6=8x +5 3.3x -4 =2x +1 4. 3x -12 =7x -8 5. 6x -4=3x +5 Tolong ya bsk di kumpulin

1 Jawaban

  • 1) 5x = 25 + 2x
    5x - 2x = 25
    3x = 25
    x = 25/3
    atau x = 8 1/3

    2) 2x - 6 = 8x + 5
    2x - 8x = 5 + 6
    -6x = 11
    x = 11/-6
    atau x = -1 5/6

    3) 3x - 4 = 2x + 1
    3x - 2x = 1 + 4
    x = 5

    4) 3x - 12 = 7x - 8
    3x - 7x = -8 + 12
    -4x = 4
    x = 4/-4
    x = -1

    5) 6x - 4 = 3x + 5
    6x - 3x = 5 + 4
    3x = 9
    x = 9/3
    x = 3
