Answer:

Step-by-step explanation:

a + c = 1000

9a + 5c = 6680

------------------------------

9a + 9c = 9000

9a+ 5c = 6680

------------------------------

4c         = 2320

c           = 580

------------------------------------------------------------

a+ 580 = 1000

a = 420

A = 420

C = 580

If you substitute the numbers into 9a + 5c = 6680, that should give you the right answer.
