\n" ); document.write( "

Let number of years when Dana will be 3 times Emma's age, be y
\n" );
document.write( "Then at that time, Emma will be 12 + y, and Dana will be 57 + y
\n" );
document.write( "We then have: 57 + y = 3(12 + y)
\n" );
document.write( "57 + y = 36 + 3y
\n" );
document.write( "y - 3y = 36 - 57
\n" );
document.write( "- 2y = - 21
\n" );
document.write( "y = , or  years 
\n" );
document.write( "The number of years should be an INTEGER, but as seen, it's not. Maybe you need to recheck
\n" );
document.write( "the problem to see if it's as you stated here.
\n" );
document.write( "You can do the check!!
