Let +a+ = the price of a cream bun
Let +b+ = the price of a mince pie
--------------------------------------
(1) +5a+=+9b+%2B+75+
-------------------------
Subtract +75+ from both sides
(1) +5a+-+75+=+9b+
Divide both sides by +9+
(1) +b+=+%28+5a+-+75+%29+%2F+9+
--------------------------------
Given:
+a+=+60+
(1) +b+=+%28+5%2A60+-+75+%29+%2F+9+
(1) +b+=+%28+300+-+75+%29+%2F+9+
(1) +b+=+225%2F9+
(1) +b+=+25+
One mince pie costs 25 p
