To find the median we have to put them all in order.
8,8,8,9,14,14,20 then take the middle number, which is 9.
To find the mean, just add all the numbers and divide by the number of numbers lol.
8+8+8+9+14+14+20=81.......81/7=11.6
Median=9
Mean=11.6

From the first equation we get y = 2x. Subbing this into the second equation, we get:
x^2 (2x)^2
------ - --------- = 1, or
25 49
x^2 4x^2
------ - --------- = 1
25 49
