if x is 6.50 and y is 4.00 and the total is 2935 but they can only have up to 450 total what would x and y be??

Assuming you mean:

6.5x + 4y = 2935

x + y = 450

 

The easiest way to solve this would be to multiply the second equation by -4

6.5x + 4y = 2935

-4x -4y = -1800

 

Add both equations

2.5x = 1135

x = 454

 

Plug x back into either equation

454 + y = 450

y = -4

 

Unless the question states it's ok to have a negative value, the system has no solution

 

I could be wrong, but unless you have anyone else to trust...>.>
