Question 992190
ashley bought 22 tickets costing 118 dollars with children tickets costing $4 each and adult tickets costing $7 each. How many adult tickets did she buy? 
-----
Equation:
a + c = 11 tickets
7a+4c = 118
-----------------------
Modify for elimination::
4a + 4c = 44
7a + 4c = 118
----------------
3a = 74
a = 24 2/3
----
Note:: The value of "a" should be a whole number.
There is probably a typo in your problem statement.

Cheers,
Stan H.
