First things first, write out two equations for your problem.\r
\n" ); document.write( "\n" ); document.write( "1: The perimeter equals 2 lengths + 2 widths. The perimeter equals 44 inches.
\n" ); document.write( "\"2l+%2B+2W+=+P\"
\n" ); document.write( "\"2L+%2B+2W+=+44\".\r
\n" ); document.write( "\n" ); document.write( "2: the width is 6 inches. \"W=6\".\r
\n" ); document.write( "\n" ); document.write( "Now combine the equations and simplify.
\n" ); document.write( "\"2L+%2B+2W+=+44\"
\n" ); document.write( "\"2L+%2B+2%286%29+=+44\"
\n" ); document.write( "\"2L+%2B+12+=+44\"
\n" ); document.write( "
\n" ); document.write( "Of course, you want to find the length. So we merely get L alone on one side fo the equation - its called isolating the variable. REMEMBER: whatever you do to one side of the equation, you MUST do to the other side.\r
\n" ); document.write( "\n" ); document.write( "\"2L+%2B+12+=+44\"
\n" ); document.write( "\"2L+%2B+12+-+12+=+44+-+12\"
\n" ); document.write( "\"2L+=+44+-+12\"
\n" ); document.write( "\"2L+=+32\"\r
\n" ); document.write( "\n" ); document.write( "Dont forget to divide by two to get the length of one side! \r
\n" ); document.write( "\n" ); document.write( "\"2L%2F2+=+32%2F2\"
\n" ); document.write( "\"L+=+16\"\r
\n" ); document.write( "\n" ); document.write( "The length is 16 inches.
\n" ); document.write( "I hope this helps you, and good luck in your math!
\n" ); document.write( "
