This DE is first order linear and is solved using the integrating factor technique. Read your class notes, textbook or a website like Linear Equations for a refresher on the method.

Can't you check it yourself? I might get hit by a bus tomorrow, then where would you be ..... Empower yourself (and it's good practice for you too):

Substitute $\displaystyle x = \pi$ and check that it gives y = 1.

Substitute the solution into the DE and check that it works.
