You can put this solution on YOUR website!
r-s=-3
\n" ); document.write( "r+s=9\r
\n" ); document.write( "\n" ); document.write( "add the two, and you'll get:
\n" ); document.write( "2r=6
\n" ); document.write( " $\"2r%2F2\"$ = $\"6%2F2\"$
\n" ); document.write( "r=3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In order to figure out the value of s, we need to multiply one set by -1
\n" ); document.write( "r-s=-3 --> $\"-r%2Bs=3\"$
\n" ); document.write( "r+s=9 -->r+s=9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "add the two and you'll get:
\n" ); document.write( "2s=12
\n" ); document.write( " $\"2s%2F2\"$ = $\"12%2F2\"$
\n" ); document.write( "s=6\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "r=3, s=6 \n" ); document.write( "

\n" );
