Consider a linear programming problem with the following constraints.

constraint $1$: $6x_1+25x_{2}63$

constraint $2$: $3x_1+36x_{2}198$

constraint $3$:$x_{1}2$

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

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