Let $\"+y+\"$ = Todd's age now
\n" ); document.write( " $\"+2y+\"$ = Chris's age now
\n" ); document.write( " $\"+y+%2B+x+\"$ = Todd's age in $\"+x+\"$ years
\n" ); document.write( " $\"+2y+%2B+x+\"$ = Chris's age in $\"+x+\"$ years
\n" ); document.write( "-----------------------------------
\n" ); document.write( "given:
\n" ); document.write( " $\"+2y+%2B+x+=+%283%2F2%29%2A%28+y+%2B+x+%29+\"$
\n" ); document.write( " $\"+2%2A%28+2y+%2B+x+%29+=+3%2A%28+y+%2B+x+%29+\"$
\n" ); document.write( " $\"+4y+%2B+2x+=+3y+%2B+3x+\"$
\n" ); document.write( " $\"+4y+-+3y+=+3x+-+2x+\"$
\n" ); document.write( " $\"+y+=+x+\"$
\n" ); document.write( "------------

\n" ); document.write( "check answer:
\n" ); document.write( "Todd is $\"+x+\"$ now
\n" ); document.write( "Chris is $\"+2x+\"$
\n" ); document.write( "In $\"+x+\"$ years, Todd is $\"+x+%2B+x+=+2x+\"$
\n" ); document.write( "In $\"+x+\"$ years, Chris is $\"+2x+%2B+x+=+3x+\"$
