Yea, so equations aren't my bestfriends, and I'm now stuck with two simultaneous equations, and I just don't know where to start, so if someone could help me and show me what to do, I'd appreciate it.
'Find the values of m such that these equations have no solutions':
3x - my = 4
x + y = 12
'Find the values of m and a such that these equations have infinite solution sets':
4x - my = a
2x + y = 4
So if someone could patiently guide me through step by step, that'd be awesome.. I hate not knowing what I'm supposed to do.
Thanks a lot
