**yuuka**, Saturday, January 21, 2012 at 11:21pmLet's say we want to eliminate 's'

So multiply 5 to the first equation

and multiply 3 to the second equation

we get:

25r - 15s = 80

9r + 15s = 90

use the elimination method by adding those two equation -15s and 15s cancels out

we get:

34r = 170

Then r = 5
