alice is twice as old as bob.in 5 years time,the total of their ages will be 70. how old is aloce now
\n" ); document.write( "

\n" );
document.write( "Then Bob's is: 
\n" );
document.write( "In 5 years, their ages will sum to 70, so their ages now sum to 60 (70 - 2 * 5, or 70 - 10)
\n" );
document.write( "We then get:  
\n" );
document.write( "2A + A = 120 ------- Multiplying by LCD, 2
\n" );
document.write( "3A = 120
\n" );
document.write( "A, or Alice is:  \n" );
