solutions of the system of equations

solutions of the system of equations

Solve the following systems of equations using the Gauss-Jordan elimination method.

X1 + x2 = 0

-x1 + x2 + x3 = -1

-1×2 + x3 = 2

Determine the solutions of the system of equations whose matrix is row equivalent to

1 0 -1 1

0 1 3 1

0 0 0 0

Give three examples.
