2x + 5y = 20

anonymous · Answer

To use a graphing method, solve for y for both equations. 
So, $$y=3-.5x$$ and
$$y=4-2/5x$$
Then, on a graphing utility, or by hand, graph them both and see where they intersect. I think that would give you the answer for part 2.

just graph the both lines and find the there intersection point
