Question

suma a doua nr este 46 cat sunt nr daca impartite da catul 7 si restul 6

Answer 1

a+b=46
a:b=7 rest 6 =) a=7b+6
____________________________
7b+6+b=46
8b=40
b=40:8=5
a=41

Answer 2

a + b =46
a ÷ b = 7,6 => a = b * 7 + 6
---
a = ?
b = ?

PRIN METODA FIGURATIVA

b |--|
a |--|--|--|--|--|--|--|-|

8 p + 6 = 46
8 p = 46 - 6
8 p = 40
p = 40 ÷ 8
p = 5.

b = 5
a = 5 * 7 + 6 => a = 35 + 6 => a = 41

VERIFICARE : 5 + 41 = 46.
