Question

A committee in Congress is made up of 19 members, and there are 9 more Democrats than Republicans on it. How many Democrats are on the committee? A) 5 B) 10 C) 14 D) 28

Answer 1

C)14

Explanation:

First off we need to define what we're looking for.

Total number of Committee Congress = 19

Let x = number of Republicans

Let x + 9 = Democrats

We add 9 to x since there are 9 more Democrats than Republicans.

x + (x+9) = 19

2x + 9 = 19

2x = 19 - 9

`(2x)/(2)=(10)/(2)`

x = 5 Republicans

Since we now know the we have five Republicans, we can then subtract the amount of Republicans to the total number of members.

19 - 5 = 14 Democrats
