You can put this solution on YOUR website!
2x+2y = 40
\n" ); document.write( "x = y + 6
\n" ); document.write( "2(y+6) + 2y = 40
\n" ); document.write( "2y + 12 + 2y = 40
\n" ); document.write( "4y = 28
\n" ); document.write( "y = 7 ft is the width
\n" ); document.write( "x = 7+6 = 13ft is the length
\n" ); document.write( ".................
