Question

Suma a trei numere este 48,a,b,c este 48.stiind ca a +b=26 si b+c=28,afla cele trei numere

Answer 1

a + b + c = 48
a + b = 26 => c = 48 - 26 = 22

a + b + c = 48
b + c = 28 => a = 48 - 28 = 20

20 + b + 22 = 48
42 + b = 48
b = 48 - 42
b = 6

a = 20
b = 6
c = 22

V. 20 + 6 + 22 = 48

Answer 2

a+b+c=48

a+b=26...=> 26+c=48...=> c=48-26...=> c=22

b+c=28...=> a+28=48...=> a=48-28...=> a=20

c+a=20+22...=> c+a=42...=> b+42=48...=> b=48-42...=> b=6

20+6+22=26+22=48
