(1) +k+%2B+s+=+25+
(2) +s+%2B+5+=+2k+
----------------------------
(2) +2k+-+s+=+5+
--------------------------
Add (1) and (2)
(1) +k+%2B+s+=+25+
(2) +2k+-+s+=+5+
-----------------------
+3k+=+30+
+k+=+10+
and
(1) +k+%2B+s+=+25+
(1) +10+%2B+s+=+25+
(1) +s+=+15+
Kyle is 10
Samuel is 15
-------------------
check:
(2) +s+%2B+5+=+2k+
(2) +15+%2B+5+=+2%2A10+
(2) +20+=+20+
OK
