Consider a linear programming problem with the following constraints.

constraint $1$:$15$X $x_1+29x_{2}72$

constraint $2$: $9x_1+48x_2=102$

constraint $3$:$x_{1}6$

Find the intersection of constraint $2$ and constraint $3.$

What is the value of $x_2$ at this point? Answer to $2$ decimal places$)$
