The value of `dy/dx` has to be determined for `e^(x/y) = 5x-y` . Using implicit differentiation gives
`e^(x/y)/y^2*(y - x*(dy/dx)) = 5 - dy/dx`
=> `(dy/dx)((x*e^(x/y))/y^2 + 1) = 5 - e^(x/y)/y`
=> `(dy/dx) = (5 - e^(x/y)/y)/((x*e^(x/y))/y^2 + 1)`
The required derivative `(dy/dx) = (5 - e^(x/y)/y)/((x*e^(x/y))/y^2 + 1)`
