Problema Solution
In the Senate, after the 2002 election, there was one senator who was Independent, and there were three more Republicans than there were Democrats. Of the 100 senators, how many were Republican and how many were Democrat?
Answer provided by our tutors
let 'd' represent the number of Democrats, then 'd+3' represents the number of republicans
100 = d + d+3 + 1
96 = 2d
d = 48
48+3=51
there were 48 Democrats and 51 Republicans
