Question

Diferenta a doua nr este 45.afla cele doua nr stiind ca împartind nr mare la nr mic obtinem catul 5 si restul 5.

Answer 1

a-b=45
a:b=5 rest 5 rezulta ca a=5xb+5
Grafic avem( aritmetic)
b l----l
a l----l----l----l----l----l+5
        [_____________]
          diferenta=45
(45-5):4=40:4=10(b) 
10+45=55 (a) primul nr.
algebric avem:
a-b=45
a=5xb+5
5xb+5-b=45
4b=45-5
4b=40
b=40:4
b=10
a=5x10+5=55

Raspuns: 55,10

Answer 2

x-y=45
x:y=5 rest 5 => x=5y+5

5y+5-y=45
4y+5=45
4y=45-5
4y=40
y=40:4
y=10

x=5×10+5
x=55
