Question 647484: I'm sorry, but question 14557 is answered incorrectly if the problem is as stated. As it appears on screen in the solution by elima, the correct solution is n= -(1/32). I don't need a reply so you can just label me as a kook.

It all depends on whether the letter n is in the denominator or not:

If it is this way   

    14 - 1%2F4n = 22

The solution is -32.

-----------------------

However, if it is this way
 
  14 - 1%2F%284n%29 = 22

The solution is -1%2F32

So you are considering the n to be in the denominator.

------

Copied exactly as it was given in 14557 

14-1/4*n=22

The order of operations (PEMDAS) say that division and multiplication are
taken by whichever comes first, so when you check it with -32
in the order of operations:

14-1/4*(-32) = 22

We do the division of 1 by 4 first and get .25, because the division
comes first going left to right.

14-.25*(-32) = 22

Next we do the multiplication:

14+8         = 22

  22         = 22

So -32 is correct by the order of operations.
