Question 1062622

Solve the system of equations
y = log_2 (2x), 
y = log_4 x.
Write your answers as ordered pairs (x,y). If you find more than one solution, list the solutions in order of increasing value of x and separate your answers with semi-colons. So, for example, you would type "(2,2);(4,6)" to say that x=2,y=2 and x=4,y=6 are the two solutions.
