Question 33168
Let B be the number of baseball cards and F be the number of football cards.


now try to form equations with the given informations.
 EQ 1.  B + F = 125
 EQ 2.  B = 5 + 3 *F

put the value of B( from eq 2) in eq 1.
 we get,
      5 + 3F +F = 125
     4F = 125 - 5

      F = 120/4
         = 30.
put F = 30 in EQ 1.,

 we get B = 125 -30
           = 95.

 Therefore  the number of baseball cards is 95 and foot ball cards is 30.
