P=2W+2L\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Given that P=6x+6 and W=x, substitute these into the equation P=2W + 2L and solve for L:
\n" ); document.write( "6x+6 = 2x + 2L\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract 2x from each side:
\n" ); document.write( "6x+6 -2x = 2x-2x+2L
\n" ); document.write( "4x+6 = 2L\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide both sides by 2:
\n" ); document.write( "\"%284x%29%2F2+%2B+6%2F2+=+%282L%29%2F2+\"
