Let +a+ = Jane's age
Let +b+ = Bob's age
------------------------------
(1) +a+=+2b+-+18+
(2) +a+%2B+b+=+63+
----------------------------
Plug (1) into (2)
(2) +2b+-+18+%2B+b+=+63+
(2) +3b+=+81+
(2) +b+=+27+
----------------------------
(1) +a+=+2b+-+18+
(1) +a+=+2%2A27+-+18+
(1) +a+=+54+-+18+
(1) +a+=+36+
----------------------------
Jane is 36
Bob is 27
