Part A:
3.14 X (4)^2 X 3/3
= 50.26548246
2x - 3y = 3.....multiply by 4
5x - 4y = 4....multiply by -3
--------------
8x - 12y = 12 (result of multiplying by 4)
-15x + 12y = -12 (result of multiplying by -3)
-------------
- 7x = 0
x = 0 <===
3+5+2+6=16 in each bag multiply or divide sorry not that much of an answer
