using matrices solve the system of equations
1/x + 1/y + 1/z= 2
2/x +1/y-3/z =0
1/x -1/y + 1/z =4
let
therefore the equations become:
writing the equations in terms of matrices,
now we will find the inverse of matrix A and then will multiply it with B.
now find the cofactor matrix
transpose of cofactor matrix is the adjoint matrix
hence u=2, v=-1 and w=1
therefore
