\n" ); document.write( " $\"+3x+\"$ = amount Karen had at beginning
\n" ); document.write( "----------------------
\n" ); document.write( " $\"+3x+-+9+\"$ = amount Karen has later
\n" ); document.write( " $\"+x+%2B+5+\"$ = amount Michael has later
\n" ); document.write( "----------------------
\n" ); document.write( "given:
\n" ); document.write( " $\"+3x+-+9+=+x+%2B+5+\"$
\n" ); document.write( " $\"+2x+=+14+\"$
\n" ); document.write( " $\"+x+=+7+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+3x+=+21+\"$
\n" ); document.write( "---------------------
\n" ); document.write( "Karen had $21 at first
\n" ); document.write( "---------------------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+3x+-+9+=+x+%2B+5+\"$
\n" ); document.write( " $\"+21+-+9+=+7+%2B+5+\"$
\n" ); document.write( " $\"+12+=+12+\"$
