<PRE><B>Question 845986</B>
 sam and mark have the same money . 
sam buys 4 sweets and has 5p left over. 
mark buys 2 sweets and has 11p left over 
form an equation where s stands for the price of sweets and how much money sam had at the start to spend
--------
Equations:
Start: S = M
S-4s = 5p
M-2s = 11p
-------
Substitute for S and for M::
4s+5p = 2s+11p
2s = 6p
======
Sam at start::
S = 2(2s) + 5p
S = 2(6p)+5p
S = 17p (amt Sam had at the start).
