\n" ); document.write( "\n" ); document.write( "Son's age = x\r
\n" ); document.write( "\n" ); document.write( "Father's age = x + 30\r
\n" ); document.write( "\n" ); document.write( "Together their ages = 36.\r
\n" ); document.write( "\n" ); document.write( "x + x + 30 = 36\r
\n" ); document.write( "\n" ); document.write( "2x + 30 = 36\r
\n" ); document.write( "\n" ); document.write( "2x = 36 - 30\r
\n" ); document.write( "\n" ); document.write( "2x = 6\r
\n" ); document.write( "\n" ); document.write( "x = 6/2\r
