240 - y equals x. Plug into the second equation. Solve for x. Then solve for y

It's not even diophantine.

It's pretty simple anon. If we rearrange both equations to find y in terms of x, we can then compare these two forms of y to evaluate x (and plug back in to any of the original equations to solve for x).

y = 240 - x
y = (33000 - 200x)/100 = 330 - 2x
240 - x = 330 - 2x
x = 330 - 240 = 90
y = 150

90 + 150 = 240
200(90) + 100(150) = 33000

Both of these check out.

Now next time pay attention in class and learn for yourself, you will never get anywhere unless you learn for yourself.
