Let x one from the equal sides and y the longer side, since the longer side measures 2 inches more than either of the shorter sides we write:
y=x%2B2. Also we know that the perimeter is 17 inches, thus we write:
y=17-2x. Now we can write the system:system%28y=x%2B2%2C+y=17-2x%29.
The solution is the point (5, 7). See the graph below.
