You can put this solution on YOUR website! what is k if the following system of equations has a unique solution:
2x+(k-1)y=6
k=1
--------
3x+(2k+1)y=9
k=-1/2
----------
2. what is k if the following system of equations has infinite solutions
kx+3y=k-3
Any value except zero.
--------------
12x+ky=k
Any value except zero
----------
3.what is k if the following system of equations has no solution
3x+2y=6
kx+(k-1)y=9
k=3
----------------
