Question

a+b+c=950
a:b=4(rest 8)
c:b=3(rest 6)
​

Answer 1

Răspuns:

a:b=4r 8, din teorema impartirii cu rest

a=4b+8

c:b=3 r 6

c=3b+6

inlocum noul a si noul c in suma

a+b+c=950

4b+8+b+3b+6=950

8b+14=950 ducem 14 cu semn schimbat

8b=950-14

8b=936

b=936:8=117

inlocuim b in formula de la a

a=4b+8

a=117×4+8

a=468+8=476

inlocuim b in formula lui c

c=3b+6=117×3+6

c=351+6=357
