you already have the information you need.
a+c = 547
10a+5c = 3775
Now crank 'er out.

Yes, you solve for a and c : )
I would suggest re-arranging a+c=547 to a = 547 - c
then subbing that into your second equation
10a + 5c = 3775 so everywhere you see the a you sub in 547 - c
10(547 -c) = 3775
now solve for c : )
then sub your answer back into your first equation.
