Hi there,
\n" ); document.write( "P= 2(a+b)
\n" ); document.write( "Divide both sides by 2
\n" ); document.write( "P/2 = 2(a + b)/2
\n" ); document.write( "Cancel out the 2's on the right hand side
\n" ); document.write( "P/2 = (a + b)
\n" ); document.write( "Remove brackets on right hand side
\n" ); document.write( "P/2 = a + b
\n" ); document.write( "Subtract a from both sides
\n" ); document.write( "P/2 - a = a + b - a
\n" ); document.write( "P/2 - a = b
\n" ); document.write( "b = P/2 - a
\n" ); document.write( "Hope this helps :-) \n" ); document.write( "

\n" );
