Question

a+b+c=6084 a-x=906 b-x=245 c-x=1925 afla a,b,c

Answer 1

a + b + c = 6084
a - x = 906
b - x = 245
c -x = 1925

dacă b - x = 245  ⇒ x = b - 245
c - x = 1925
c - (b - 245) = 1925
c - b + 245 = 1925
c - b = 1925 - 245
c - b = 1680 
c = b + 1680

a - x = 906
a - (b - 245) = 906
a - b + 245 = 906
a -b = 906 - 245
a - b = 661
a = b + 661

a + b + c = 6084
(b + 661) + b + (b + 1680) = 6084
3b + 2341 = 6084
3b  = 6084 - 2341
3b = 3743
b = 3743/ 3
a = b + 661
a = 3743/3 + 661 = (3743 + 1983) / 3 = 5726 / 3
c =b + 1680
c = 3743/ 3 + 1680 = (3743 + 5040)/3 = 8783 / 3
