You're seeking to find MARY'S age, so let MARY'S age be M
\n" );
document.write( "Then Sue's is: M - 5
\n" );
document.write( "We then get: \"matrix%281%2C3%2C+M+-+5+-+20%2C+%22=%22%2C+%281%2F2%29+%2A+M%29\"
\n" );
document.write( "\"matrix%281%2C3%2C+M+-+25%2C+%22=%22%2C+M%2F2%29\"
\n" );
document.write( "2M - 50 = M ------- Multiplying by LCD, 2
\n" );
document.write( "- 50 = M - 2M
\n" );
document.write( "Mary, or
