Let the total money be = $ x

                                         x
Then Sam has spent = --- + 10
                                          2

                                     x
This is the same as  ---- + 60
                                      7

Equating the two we get

   x                     x
---- + 10 = ------ + 60
   2                      7

   x            x
----  -  -----  = 60 - 10
   2             7

7x - 2x
-------  =  50
   14

multiplying both sides by 14 (basically to get rid of denominator 14 on LHS), we get

7x - 2x = 50 x 14

so 5x = 700

so x = 700/5 = 140

So, to begin with Sam had $140
