In november 2005, Google and Yahoo search engines were used to conduct a total of 3.57 billion online searches. Google was used to conduct 0.53 billion more searches than yahoo. How many searches were conducted on each search engine?
----------------------------
Equations:
G + Y = 3.57 billion
G = Y + 0.53
---------------------
Substitute to solve Y:
Y + 0.53 + Y = 3.57
2Y = 3.04
Y = 1.52 billion (# of Yahoo searches)
----
G = 1.52+0.53 = 2.03 billion (# of Google searches)
