---------------
Equations:
Quantity Eq: p + a = 12 kg
Value Eq:: 8.3p+6.5a = 6.95*12
----------------------------------------
Multiply thru Quantity by 830
Multiply thru Value by 100
----------------------------------
830p + 830a = 830*12
830p + 650a = 695*12
--------------------------
180a = 135*12
a = 9 (# of kg of apples)
---
p = 12-9 = 3 kg (# of kg of apricots)
