**Damon**, Monday, December 28, 2009 at 11:00amDr WLS gave you the answer but I will elaborate:

The answer is in both set A and in set B since it is the intersection.

Therefore the question is: Where is 3x-4 also 2x+5.

To find out for what x this is true, set them equal.

3x-4=2x+5

3x-2x = 5+4

x = 9
