Explicație pas cu pas:
1.Vom inmulti prima relatie cu 7 si a doua cu 5.
2.5 saci grau...............6 saci porumb................257kg|×7
7 saci grau...............9 saci porumb................373kg|×5
35 saci grau............42 saci porumb...............1799kg
35 saci grau............45 saci porumb................1865kg
0 saci grau............. 3 saci porumb.................96kg
1 sac porumb..................32kg
5 saci grau............6×32kg porumb.................257kg
5 saci grau............192 kg porumb..................257kg
5 saci grau............65kg
1 sac grau............13kg
8×13kg+8×32kg=104kg±256kg=360kg, deci ,,da” poate cara cate 8 saci din fiecare.
