Solve the following LP problem graphically by enumerating the corner points. $($If there is no solution, enter NO SOLUTION.$)$

MAX: $3$X$1+4$X$2$

Subject to: X$1<=13$

X$2<=10$

$4$X$1+6$X$2<=88$

X$1,$ X$2>=0$

What is the optimal solution?

$($X$1,$ X$2)=$

What is the optimal objective function value?
