In the 75th Congress (1937−1939) there were in the Senate 75 Democrats, 17 Republicans, and 4 members of other parties. Suppose that a bill passed the Senate with 40 more votes in favor than against, with three times as many Democrats voting in favor as non-Democrats voting in favor, and with 38 more Democrats voting in favor than Republicans voting in favor. 

If every member voted either for the bill or against it, how many Democrats, how many Republicans, and how many members of other parties voted in favor of the bill? How many democrats? How many Republicans? Other party members?
