Let's make $\"X=age\"$ for all reference.
\n" ); document.write( "1st condition:
\n" ); document.write( " $\"Sue=X%28years%29\"$ , Sue's age
\n" ); document.write( " $\"Leah=X%2B6%28years%29\"$ , leah being 6 years older than Sue
\n" ); document.write( "2nd condition:
\n" ); document.write( " $\"John=X%2B6%2B5%28years%29\"$ , John being 5 years older than Leah
\n" ); document.write( "Equating to totasl age:
\n" ); document.write( " $\"x%2Bx%2B6%2Bx%2B6%2B5=41years\"$ --------> working eqn
\n" ); document.write( " $\"3x=41-6-6-5\"$
\n" ); document.write( " $\"3x=24\"$ -------------> $\"cross%283%29x%2Fcross%283%29=cross%2824%298%2Fcross%283%29\"$
\n" ); document.write( " $\"x=8\"$ years old (Sue)
\n" ); document.write( "Leah= $\"8%2B6=14\"$ , 6 years older than Sue
\n" ); document.write( "John= $\"8%2B6%2B5=19\"$ , 5 years older than Leah
\n" ); document.write( "In doubt? go back to our condition & working eqn.
\n" ); document.write( " $\"8%2B8%2B6%2B8%2B6%2B5=41\"$
\n" ); document.write( " $\"41=41\"$
\n" ); document.write( "Thank you,
