Homework Help: Algebra

Posted by A.W. on Friday, March 6, 2009 at 4:53pm.

How do I solve for elimination method on this problem: 0.3x - 0.2y=4 and 0.3x + 0.3y= 5/19. I know that multiply by 10 on both equations and get 3x-2y=40 and 3x+3y=50/19. and then I have to multiply 3x-3y=40 by 3 and 3x+3y= 50/19 by -3 to get 9x-9y=120 and -9x-9y=-150/19. But from there I get lost. Can someone please help me?
