Question

dacă a+b+c=529 si b+c=119,calculati:a;a-(b+c);b+c-19;a+b+c-500.

Answer 1

a+b+c = 529
b+c = 119
a+119 = 529
a = 529 - 119
a= 410
a- ( b+c) = 410 - 119 = 291
b+c - 19 = 119 - 19 = 100
a+b+c -500 = 529 - 500 = 29

Answer 2

a=(a+b+c)-(b+c)
a=529-119=410
a-(b+c)=410-119=291
b+c-19=119-19=100
a+b+c-500=529-500=29
