Add $\"+x+\"$ to both ages and make the sum = 150
\n" ); document.write( " $\"+34+%2B+x+%2B+68+%2B+x+=+150+\"$
\n" ); document.write( " $\"+2x+%2B+102+=+150+\"$
\n" ); document.write( " $\"+2x+=+48+\"$ answer
\n" ); document.write( " $\"+x+=+24+\"$
\n" ); document.write( "In 24 years their ages will add up to 150

\n" ); document.write( " $\"+68+%2B+24+=+92+\"$
\n" ); document.write( " $\"+58+%2B+92+=+150+\"$
\n" ); document.write( "OK
