2L+2W=66
\n" ); document.write( "LxW=216\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so start with 2L+2W=66 lets solve for W
\n" ); document.write( "2L+2W=66
\n" ); document.write( "-2L -2L
\n" ); document.write( "2W=66-2L
\n" ); document.write( "divide everything by 2
\n" ); document.write( "2w/2=w 66/2=33 -2L/2=-L
\n" ); document.write( "so new equation is w=33-L ok lets start on the 2nd equation
\n" ); document.write( "LxW=216
\n" ); document.write( "replace W with (33-L)
\n" ); document.write( "Lx(33-L)=216
\n" ); document.write( "-L^2+33L=216
\n" ); document.write( "so L=9
\n" ); document.write( "ok lets find W now
\n" ); document.write( "2(9)+2W=66
\n" ); document.write( "2W=48
\n" ); document.write( "W=24
\n" ); document.write( "L=9
\n" ); document.write( "24x9=216
\n" ); document.write( "
\n" ); document.write( "
\n" );
