You can put this solution on YOUR website!
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:\r
\n" ); document.write( "\n" ); document.write( " $\"y=x%2B2\"$ . Also we know that the perimeter is 17 inches, thus we write:\r
\n" ); document.write( "\n" ); document.write( " $\"y=17-2x\"$ . Now we can write the system: $\"system%28y=x%2B2%2C+y=17-2x%29\"$ .\r
\n" ); document.write( "\n" ); document.write( "The solution is the point (5, 7). See the graph below.\r
\n" ); document.write( "\n" ); document.write( " $\"graph%28600%2C+600%2C+-5%2C+10%2C+-5%2C+20%2C+x%2B2%2C+17-2x%29\"$ . \n" ); document.write( "

\n" );
