Steps -------->
- First calculate the determinant of the matrix say, D
- Then calculate Dx determinant with first column replaceable with Xb.
- Similarly calculate Dy detreminant with second clumn replaceable with Xb
- And then Dz by replacing with third column replaceable with Xb.
if D =0 AND Dx Dy and Dz is non-zero then No- Solution.
if D is non- zero Unique soln.
if D = 0 Dx =0 Dy =0 and Dz =0
then infiniite solution.
