    Gaussian elemination and fraction problem

    hey guys i have a bit of problem with a very basic thing here.. here is the problem :
    i need to solve these equation by using Gaussian elimination method but i cannot put this equation in 4x4 matrix becoz its fraction.if it was a linear equation like 1x+2y-3Z=0 i can simply form a matrix. again i know how to solve the Gaussian elimination method but i cannot form the augmented matrix.

    1/x+2/y-1/z=1
    2/x+4/y+1/z=5
    3/x-2/y+2/z=0

    i appreciate your help guys

    Define three new variables: t = 1/x, u = 1/y, v = 1/z. Solve for t, u, v using regular Gaussian elimination, then solve the equations I just wrote down for your x, y, z.
