Sneaky! Very, very sneaky - but cute, I guess - my reaction varies!
Easy but fun.
I thought it was difficult.
that was a very wierd teaser. It made me think of school again...Cool!
I guess the answer can vary. X could equal 2. 2 x 2 = 4. So C can equal 4. But I like your thinking.
cool!
An alternate solution is:
X=square root of c
C=x squared
X=square root of c
C=x squared
Math is not my strongest point so I gave up and looked at the answer. Talk about feeling really, really stupid!!!! So simple that I made it difficult. Good job.
There was no way to think it would represent Roman Numerals, so I just thought ... 'they have nothing to do w/ the equation so there isn't enough info'
I was wrong
