    (10-7x)/(6-7x)=(5x-4)/(5x)

    5x(10-7x) = (5x-4)(6-7x)

    50x - 35x² = -35x²+28x+30x-24

    50x = 58x-24

    8x = 24

    x = 3

  • Not sure if its right:

    (10-7x)over(6-7x)=(5x-4)(5x)

    = ((7x)x(5x))over(6-7x)=(-20)over(10)

    = (35x)over (-7x)=((-20)x6)over(10)

    = (35x)devided by(-7x)=(120)Devided by(10)

    = (-5x) = 12

    Therefore x = 2.4

    (I hope this is right... lol)

    INVALID EQUATION!

    tell what (5x-4) is over.
