A farmer sells a bushel of soybeans for $5 and a bushel of corn for $3. If he hopes to earn $164 and plans to sell 40 bushels in all, how many bushels of soybeans does he need to sell?

anonymous · Answer

$$(5x+3y)=164 $$

anonymous · Answer

and $$x+y=40$$

anonymous · Answer

seewht you can do with those first

lilai3 · Answer

uhm...idk

anonymous · Answer

all right this needs some trial and error work
first write down possible combinations to get to forty that seem reasonable.

anonymous · Answer

then plug in these numbers until you get an answer that fits.

lilai3 · Answer

uhmm....5(40-y)+ 3y=164....
???? idk if it's right most likely it's gonna be wrong :P

anonymous · Answer

try it.

anonymous · Answer

the worst possible outcome is that you are wrong. its no big deal.  just plug your answer it into the original two i gave you to check if you are right.

lilai3 · Answer

then i don't get it at all then

anonymous · Answer

i hope im not making things worse.

lilai3 · Answer

don worry ur not :DDD

accessdenied · Answer

Or you could solve the system using Algebra
  5x + 3y = 164
    x +   y =   40 
This one is pretty easy to solve using substitution or elimination.
I think solving it using the Algebra would be a little more direct than trial than error, at least.

lilai3 · Answer

that's y its called help and thank you @accessdenied!

lilai3 · Answer

uhm....?/?????

accessdenied · Answer

Well, if we wanted to use substitution, we could solve for a variable in the second equation, and then substitute it back into the first to solve since it'll be one-variable.
  x + y = 40
     - y    -y
  x = 40 - y
Which we can plug back into the first:
  5(x) + 3y = 164           Replace 'x' with above
  5(40 - y) + 3y = 164
then from there we could solve for the y-value, and plug it back into the first equation.

accessdenied · Answer

plug the y-value back into the second equation, rather.  (I am referring to the 1st equation as 5x + 3y = 164 and 2nd is x + y = 40)

thank you i understand now thank you SO VERY MUCH!!!!!!!!!!!!!!!!!!!!!

accessdenied · Answer

You're welcome.  :)

lilai3 · Answer

:DDD
hope you have a great day

accessdenied · Answer

Thank you.  To you as well.  :)

lilai3 · Answer

wait i haf a queston:
uhm....what is the equation thtat you plug in and what did you geT?

accessdenied · Answer

5(40 - y) + 3y = 164
 200 - 5y + 3y = 164
 200 - 2y = 164
 100 - y = 82
 -y = -18
  y = 18   --->  x + y = 40

  x + 18 = 40
  x = 22

lilai3 · Answer

omfg now for REAL i understand

accessdenied · Answer

Hmm.  :P
Good!

whew i wub ur gelp, bro!
