what does simplify answer mean

Question

My class this week is asking me to Simplify my answer to this problem.  

 

3x-2y+4

3y-2x

 

So I know that x=8 and y=6

 

so 3*8-2*6+4

    3*6-2*8

 

24-12+4 = 16

18-16     = 2     = 2

 

but it won't take any of my answers as being simplified

 

Answer 1

If the original problem is (3x-2y+4)/(3y-2x), then everything you have shown here is correct up to the final calculation. Your work for getting to the point of 16/2 is correct, but 16/2 would simplify to 8 and not 2 as you indicated. If 8 is not a solution to the problem, it sounds like the question you are working on is not properly designed which is not your fault!
