Factor 3125 -> 5^5
so
5c^4-3125
=5c^4-5^5
=5(c^4-5^4)
=5(c^2+5^2)(c^2-5^2)
=5(c^2+5^2)(c+5)(c-5)

Use a calculator?
C+A=342
$5C+$12A=$2,550
5C+5A=1710
5C+12A=2550
-7C=-840
C=120
5(120)+12A=2550
600+12A=2550
12A=1950
A=163
You could do 0.9 1.6 3.5 dont know of thats what you ment but they all have decimals :)
