Question

The US 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

48 Republicans and 52 Democrats.

Explanation:

Let the number of Republicans be `x`.
There are `x+4` Democrats.

Thus, `x+(x+4) = 100`
`implies2x = 100-4`
`implies x = 96/2 = 48`

There are 48 + 4 = 52 Democrats.
