Solve 16.7 only please. I attached 16.5 for reference

16.5 Solve equation (16-19) for the temperature distribution in a plane wall if the internal heat generation per unit volume varies according to q=q0ex/L. The boundary conditions that apply are T=T0 at x=0 and T=TL at x=L. 16.7 Solve Problem 16.5 for the same conditions, except that at x=L,dT/dx= (a constant)
