m=mere

p=pere

c=capsuni

2m+4p+3c=54 lei |

4m+100+7c=128 lei | => m=? ; p=? ; c=?

6m+6p+4c=86 lei |

2m+4p+3c=54 lei

6m+6p+4c=86 lei

8m+10p+7c=140 lei

4m+10p+7c=128 lei

____________________

4m+0p+0c=12 lei

4kg m=12 lei

m=12:4

m=3 lei (1 kg de mere)

6m+6p+4c=86 lei

2m+4p+3c=54 lei

_________________

4m+2p+1c=32 lei

4kg m×3+2kg p+1kg c=32 lei

12lei+2kg p+1kg c=32 lei

2kg p+1kg c=32-12

2kg p+1kg c=20 lei

4m+10p+1c=128 lei

4m+2p+1c=32 lei

____________________

0m+8p+6c=96 lei

2kg p×4+1kg c×4=20×4

8kg p+4kg c=80 lei

_____________________

0p+2c=12 lei

2kg c=16 lei

1kg c=16:2

1kg c=8 lei

2m×3 lei+4p+3c×8 lei=54 lei

6 lei+4p+24 lei=54 lei

4kg p=54-30

4kg p=24 lei

1kg p=24:4

1kg p=6 lei

Verific:

2×3+4×6+3×8=6+24+24=30+24=54 lei (2kg m+4kg p+3kg c)

4×3+10×6+7×8=12+60+56=72+56=128 lei (4kg m+10kg p+7kg c)

6×3+6×6+4×8=18+36+32=54+32=86 lei (6kg m+6kg p+4kg c)

1kg m=3 lei

1kg p=6 lei

1kg c=8 lei, 《 ok ! 》
