The Maths Prof: Rates of Change, Derivatives (Part 2) 

'A point moves along a curve y=8/(7-2x). As it passes through the point P, the x-coordinate is increasing at a rate of 0.125 units per second and the y-coordinate is increasing at a rate of 0.08 units per second. Find the possible x-coordinates of P.'
