Use Gauss-Jordan elimination to solve the following systems of linear equations, or state that there are no solutions.

a)

4?+8?=−4

−3?−6?=5

b)

?+4?−?=8

2?+8?+?=1

you should find that the system has infinitely many solutions. Introduce a parameter in order to give the general solution. Then give one particular solution.
