Barry is 6 years older than his sister sue. Three years ago he was twice as old as sue was then. How old is Barry now?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let Barry’s age now be B
\n" ); document.write( "Then Sue’s age now is B – 6\r
\n" ); document.write( "\n" ); document.write( "Three (3) years ago, Barry was (B – 3) years-old
\n" ); document.write( "Three (3) years ago, Sue was (B – 6 – 3), or (B – 9) years old\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since 3 years ago, Barry was twice Sue’s age then, then we’ll have: B – 3 = 2(B – 9)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "B – 3 = 2B – 18
\n" ); document.write( "- B = - 15
\n" ); document.write( "B, or Barry is now: \"%28-15%29%2F-1\", or \"highlight_green%2815_years-old%29\"\r

\n" ); document.write( "----------\r
\n" ); document.write( "\n" ); document.write( "Barry is now 15 years-old, so 3 years ago he was 15 – 3, or 12 years-old
\n" ); document.write( "Sue is now 9 (15 – 6) years-old, so 3 years ago she was 9 – 3, or 6 years-old\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Three (3) years ago, Barry (12 years-old then) was twice Sue’s age (6 years-old then).\r
