2.50x + 1.75y < or = to 15

y < or = 1.43x + 8.57

y = 8.57

I'm having a brain cramp and trying to find x has been a lost time tonight. Plese help what is x

The second inequality can be derived from the first one.

The third statement, y=8.57, does not follow from the second. Is it independent information that you were given?

If y=8.57, then

8.57 <or= 1.43 x + 8.57

0 <or= 1.43 x

x >or= 0
