Solving Linear Equations: Finding the Solution Set for m
From the equation 'mx-1=2x', rearranging and combining terms, we have '(m-2)x=1'. Therefore, 'x=1/(m-2)'. Since the equation 'mx-1=2x' has a solution as a positive real number, we have '1/(m-2)>0'. Solving this inequality, we find that 'm>2'. Therefore, the correct option is C.
