Let $\"+x+\"$ = Annie's age now
\n" ); document.write( "Just look at the part that says
\n" ); document.write( "\"when Alma was as old as Annie is now\"
\n" ); document.write( "That means that Alma was $\"+x+\"$ years old
\n" ); document.write( "The difference in their age will always be $\"+36+-+x+\"$
\n" ); document.write( "That means that when Alma was $\"+x+\"$ years old,
\n" ); document.write( "Annie was $\"+x+-%28+36+-+x+%29+=+2x+-+36+\"$
\n" ); document.write( "It says that Alma is now twice that age, so
\n" ); document.write( " $\"+36+=+2%2A%28+2x+-+36+%29+\"$
\n" ); document.write( " $\"+36+=+4x+-+72+\"$
\n" ); document.write( " $\"+4x+=+108+\"$
\n" ); document.write( " $\"+x+=+27+\"$
\n" ); document.write( "Annie is 27
\n" ); document.write( "-----------
\n" ); document.write( "check:
\n" ); document.write( "When Alma was 27, that was 36 - 27 = 9 years
\n" ); document.write( "ago. Annie was 27 - 9 = 18
\n" ); document.write( "Alma is twice that age, or 2x18 - 36
\n" ); document.write( "OK \n" ); document.write( "

\n" );
