6 eclere...4 savarine..50,lei
______________________
                2 savarine = 10 lei => 1s = 5 lei
6e+4s=50
6e=50-20
6e=30 => e=5lei

4kg z ....30 kg f ....72 lei -
2kg z ....30 kg f ....66 lei

2kg z ......................6 lei => 1kg z = 3lei

2kg z+30 kg f = 66
6+30 kg f = 66
30kg f = 60
1kg f = 2lei
