System of linear congruences... Help, please!

[MathExpert]

5x == 200 (mod 251)
11x == 192 (mod 401)
3x == -151 (mod 907)

first find the inverses of 5, 11 and 3 modulo 251, 401, 907 resp. to make it easier to solve. do this using eulcid's algorthim if you do'nt see what the inverse are straigh away. hint 5*50=250, and 3*302=906.

then use the chinese remainder theorem on the first two to reduce to two equivalences, then repeat.
