This is a first-order linear differential equation in two unknown functions (p(t) and o(t)).
It cannot be solved uniquely unless you give one of the following:
1. A second equation relating p and o
2. An explicit expression for o(t) so we can solve for p(t), or vice versa
3. A relationship like o=kp
4. Initial conditions and a known functional form for one variable
