    I. The method. Let with f a continuous function. There is a simple trick to solve this type of differential equation: let us introduce the auxiliary function

    (recall that y is a function of x). Then:

    and So, by simple substitution, we get:

    which is very easy to solve!

    Example: to solve we put u=x+y+3, so we have to solve:

    because a=b=1 in this case. The ...
