Which of the following have one solution, solve for :P

C only

Step-by-step explanation:

C is the only one which is correct as in all the other options x is cancelled out as both sides have 2x which gets cancelled leaving the equation with something like:

31=31 which is true but it's not considered a "solution" and as A, B and D end up with stuff like this they are all not 1 solution. For c, as c doesn't have a power on top of it, like does, its equation can only have 1 solution (or in some cases 0 solutions but this isn't one of them) so it is the correct answer.

the answer is 31.27mph
