Try this:
\n" ); document.write( "Let the two numbers be a and b, then:
\n" ); document.write( "a+b = 52 and
\n" ); document.write( "a = 3b Substitute this for a in the first equation.
\n" ); document.write( "3b+b = 52 Simplify.
\n" ); document.write( "4b = 52 Divide both sides by 4.
\n" ); document.write( "b = 13 and
\n" ); document.write( "a = 3(13)
\n" ); document.write( "a = 39
\n" ); document.write( "Check:
\n" ); document.write( "13+39 = 52.
\n" ); document.write( "
\n" ); document.write( "
\n" );
