A first order linear differential equation is a diff. equation such that
$$P(x)*y + dy/dx = Q(x)$$
where $P$ and $Q$ are continuous functions on the interval. To solve this equation, we multiply both sides by integrating factor $I(x) = e^{\int P(x) dx}$ to put it in the form...
$(I(x)y)' = I(x)*Q(x)$.
This is solved by integration.
