Consider the linear programming problem where x and y are the decision variables.

Maximize $6\backslash$times $+8$y

subject to the following five constraints

$[$C$1]5$x$+2$y $<=40$

$[$C$216\backslash$times $+6$y $<=60$

$[$C$3]2$x$+4$y $<=32$

$[$C$41$ x $>=0$

$[$C$5]$ y $>=0$

Which two constraints control the solution?
