Solving differential equations Mathcad prime 2

Hi

I am new to MC Prime 2.0, but I have been using MC 2001i and MC 14 at High School, but license expired when I graduated.

On to the issue:

I want Mathcad to solve some differential equations and give me out the function as a result like

y'(x) = x+5y/4^2

y(0)=2

and then I press

y(x) = <answer comes here>

and out comes the function that matches those conditions. I have no idea of how to this, except something about that ODESolve, but I can't figure out how to use it, and the web isn't at any help at all (neither the built in tutorial).

By the way, it is all random numbers that I just pressed in the example
