Notice that for a system of linear eqns to have infinite solutions, the RREF cannot be a Id matrix.
As such, you could have
1 0 0
0 1 0
0 0 0
Or
1 0 0
0 0 1
0 0 0
as combinations of a 3rd variable being arbitrary.
Could you use this to figure out how to make 2 out of 3 variables have arbitrary values while fixing the first?

Hi! For the matrix A, if your teacher wants it in RREF, you cannot have a * as an entry, since that can be simplifies further. Only the solution matrix b can have *.
