solve the system of equations

**Emily**, Saturday, September 12, 2009 at 11:14pmIt gives you the value of x, so substitute that value into the first equation, like this:

x + 3y = 2

x = 9 - 3y

9 - 3y + 3y = 2

9 = 2

Somehow, you get 9 = 2, which is DEFINITELY not correct, so maybe there was a typo in typing out the question?
