Homework Help: Simple (?) problem

  1. Jan 13, 2009 #1
    First of all excuse my English.

    I have the following problem and I don't know if it can be solved.

    We have the following equations:

    A*X1=B*X2=C*X3=D*X4=E*X5=F*X6 and


    If we know the values of A,B,C,D,E,F can we found the values of X1,X2,X3,X4,X5,X6?

    Can anyone help me?
    Sorry if I didn't make the post in the correct category

    Yep it can be done.

    The way that i would solve it would be to form the six equations:

    AX1 = c
    BX2 = c
    FX6 = c

    Where c is some fixed constant. Can you see how i can form these equations?

    You can then easily use these separate equations along with the last equation (X1+X2+X3+X4+X5+X6=100) to find what the constant c is, and hence what each X is.
