x.....?
y......?

1 Jawaban

  • 2/x + 1/y = 1 1/5
    2/x + 1/y = 6/5
    2/x = 6/5 -1/y
    2y/x = 6/5 -1
    2y = 1/5x
    y = 1/10x

    1/x - 3/y = -1/10
    1/x - 3/ (1/10x) = -1/10
    1/x - 30x = -1/10
    1 - 30x = -1/10x
    -30x + 1/10x = -1
    1-300x²/10x = -1
    -300x²/10x = -1 -1
    -30x = -2
    x = -2/-30 = 1/15

    y = 1/10x
    y = 1/10.1/15
    y = 1/ 10/15
    y = 1/ 2/3
    y = 3/2

    Maaf, klo salah
