Let Beth’s age, be B
\n" );
document.write( "Difference in ages: 7
\n" );
document.write( "Beth was Una’s age, 7 years ago, or she was: B - 7, at which time, Una was B - 7 - 7 = B - 14
\n" );
document.write( "We then get: B = 2(B - 14)
\n" );
document.write( "That's the ONLY equation you need, which you can use to determine B's (Beth's) age. \n" );
