Find all solutions of:

2x + 2y + 4z = 8

x - y + 2z = 2

-x + 5y - 2z + 2

First we describe the given equations as a matrix. And then we use Linear algebra to solve the given equations. There are many methods to do so. Let us try

1. Try using Cramer\'s rule : But the matrix has zero determinant !!

2. Try using inverse matrix : Cannot compute inverse for singular matrixes.

This must mean that the system does not have a unique solution but has an infi...
