Let $\"+x+\"$ = Colin's age now
\n" ); document.write( " $\"+x+%2B+12+\"$ = Paul's age now
\n" ); document.write( " $\"+x+-+3+\"$ = Caroline's age now
\n" ); document.write( "---------------------------------------
\n" ); document.write( " $\"+x+%2B+%28+x+%2B+12+%29+%2B+%28+x+-+3+%29+=+87+\"$
\n" ); document.write( " $\"+3x+%2B+9+=+87+\"$
\n" ); document.write( " $\"+3x+=+78+\"$
\n" ); document.write( " $\"+x+=+26+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+x+%2B+12+=+38+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+x+-+3+=+23+\"$
\n" ); document.write( "--------------------
\n" ); document.write( "The youngest is Caroline
\n" ); document.write( "who is 23
\n" ); document.write( "------------------------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+26+%2B+38+%2B+23+=+87+\"$
\n" ); document.write( " $\"+87+=+87+\"$
\n" ); document.write( "OK \n" ); document.write( "
