Question

The U.S. Senate has 100 members. After a certain election, there were 4 more Democrats than Republicans, with no other parties represented. How many members of each party were there in the Senate?

Answer 1

Let x = # of Republicans

x + 4 = # of Democrats

x + x + 4 = 100

x = 48

48 + 4 = 52

There are 52 Democrats and 48 Republicans.
