y-----------> </span><span>the width of the frame
we know that
Perimeter of the frame=2*(x+y)
2*(x+y) <=96
x>=(y-4)</span>²
using a graph tool
see the attached figure
<span>the solutions that are viable are those in which the values of x and y are positive belonging to the total solution of the system</span>
