Question

Afla numerele a, b, si c stiind ca;
a) a+b=46 895;
b) b+c=41 693
c) a+b+c=57 113

Answer 1

a) a+b=46 895;

b) b+c=41 693

c) a+b+c=57 113  

46895 + c = 57113 ⇒ c = 57113 - 46895 = 10218

b + 10218 = 41693 ⇒ b = 41693 - 10218 = 31475

a + 31475 = 46895 ⇒ a = 46895 - 31475 = 15420

Answer 2

b+c=41 693
a+b+c= 41 693

a+41 693=57 113
a= 57 113-41 693
a= 16 720

a+b= 46 895
16 720+b= 46 895
b= 46 895- 16 720
b= 30 175

b+c=41 693
30 175+c= 41 693
c= 41 693-30 175
c= 11 518
