Solve matrices using Gaussian elimination or...

Gauss-Jordan elimination.

This is a word problem and I'm not very good at these, so please help.

eAuction.com spent a total of $11 million on advertising in fiscal years 2001, 2002, and 2003. The amount spent in 2003 was 3 times the amount spent in 2001. The amount spent in 2002 was $3 million less than the amount spent in 2003. How much was spent on advertising each year?

I'm not sure if this is how I should proceed but this is a far as my brain would stretch...

x = 2001

y = 2002

z = 2003

x + y + z = $11 million

I'm rambling here:

3z - x = ?

z - 3,000,000 = y

How do you use Gaussian elimination or Gauss-Jordan elimination to solve this? :confused:Thanks in advance.
