This is a conditional equation. If we were to replace c with 1 for example, then
our equation would say 598 equals 92 times 1. We could simplify that to say that
598 equals 92, but we know that that's not true, 598 is not equal to 92. That
means that there are some values of c for which this equation is not true, so we
know already that this is not an identity.
I'll tell you right now, though, that this last choice, that this is not an
equation, is incorrect. There is, in fact, one value for which this equation is
true. Our next step is going to be to find that value.
