Answer 1

Răspuns:

Explicație pas cu pas:

Notam :

|,,,,,,,,,,,,,|= numarul care se scade

|,,,,,,,,,,,,,| +9

|,,,,,,,,,,,,,| +15

|,,,,,,,,,,,,,| +11

|,,,,,,,,,,,,,| +12

------------------------------------- (+)

4*|,,,,,,,,,,,,,| +9+15+11+12 = 67

4*|,,,,,,,,,,,,,| = 67 -9-15-11-12

4*|,,,,,,,,,,,,,| =20

|,,,,,,,,,,,,,| =5

Numerele sunt :

5+9=14

5+15=20

5+11=16

5+12= 17

Verificare : 14+20+16+17=67
