    reduction of order?

    i'm looking at a question that asks to reduce the following second order equation to a frist order and find the solution

    y"+y'=x+1

    does this mean reduction of order?

    It means put v=y', then the equation becomes:

    <br />
v'+v=x+1<br />

    which is of first order rather than second.
