Homework Help: Algebra (Intermediate)

Posted by JerryJ on Monday, October 11, 2010 at 1:49pm.

5. Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.

9x + 6y = 60
-27x Ð 18y = -180

Here's where I am at now:

9x(3) + 6y(3) = 60
27x +18y + 60

27 x + 18y = 60
-27x -18y = 180

Im stuck here because the x and y appear to cancel.

Any suggestions or assistance anyone?
