**Reiny**, Tuesday, March 11, 2008 at 4:16pmThis is the second time I have seen your question.

I did not answer it the first time since I could not decide what you meant.

1. Is it (1/2)x ... or is it 1/(2x)...

2. why would they have 3-1/2 on the right side? Is there a variable missing?

3. are you solving the first for x in terms of y??

4. in the second, are you solving for y in terms of x?

5. For their graphs, both would be straight lines that intersect, their intersection point is the solution to the system

6. I would solve the second equation for x, then sub that back into the first.
