Expert Solution
Step 1

Given second order differential is 

xy''+y'=60x

As x & y are positive , then we can divide both sides in above by x.

That is ,

y''+1xy'=60              - (1)

Now let us assume x=ez  or z=logx , then 

dydx=dydz·dzdx=1x·dydz                                         z=logx
