The equation for the perimeter of a rectangle is P = 2L + 2W.
\n" ); document.write( "Equation 1: \"66+=+2L+%2B+2W\"
\n" ); document.write( "Equation 2: \"L+=+3+%2B+5W\"
\n" ); document.write( "Plug (3 + 5W) into equation 1 for L.
\n" ); document.write( "\"66+=+2%2A%283+%2B+5W%29+%2B+2W\"
\n" ); document.write( "Multiply the 2 through.
\n" ); document.write( "\"66+=+6+%2B+10W+%2B+2W\"
\n" ); document.write( "Combine like terms.
\n" ); document.write( "\"66+=+6+%2B+12W\"
\n" ); document.write( "Subtract 6 from both sides.
\n" ); document.write( "\"60+=+12W\"
\n" ); document.write( "Divide both sides by 12.
\n" ); document.write( "\"highlight%285+=+W%29\"
\n" ); document.write( "Now plug 5 into equation 2 for W and solve for L.
\n" ); document.write( "Equation 2: \"L+=+3+%2B+5W\"
\n" ); document.write( "\"L+=+3+%2B+5%2A%285%29\"
\n" ); document.write( "\"highlight_green%28L+=+28%29\"
\n" ); document.write( "
\n" );
