Simple variable puzzle

1) You can't have ambiguity. You can't have "2x squared" meaning (2x) squared = 4x2 and have
"4x squared" meaning 4x2 also.
2) "x" and "X" are different cases of the same letter, and therefore they represent different variables.
So, it would be consistent for those two equations to exist, because you have two different
variables in them.
