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
