Math Help - Linear Algebra Proof

Question:
Suppose a and b are real numbers, not both 0. Find real numbers c and d such that 1/(a+bi)=c+di. (i as in the imaginary number.)


So far I have reworked the equation into

1=ac+adi+cbi-bd.

Not sure where to go from here. Just need a little push in the right direction. THANKS!!!
