    yes, you do because x cannot be multiplied

    so...

    7/x-3=4/x-5

    7x-35=4x-12

    7x-4x= -12+35

    3x=23

    x=23/3

    x= 7 2/3 (seven and two thirds)

    Yeah, u cross multiply.

    7/x-3=4/x-5

    7(x-5)=4(x-3)

    7x-35=4x-12

    7x-4x= -12+35

    3x=23

    x=23/3

    x=7.6667

    x=7.67

    I believe you have a mistake in your original problem, (x^2+x+7) is probably supposed to be (x^2+x-7) That factors to (x-3)(x+4) Hopefully that helps you to solve it yourself.
