Сумма 3 чисел равна 1000 сумму 1 2 числа 1 650 сумму 2 и 3 550 узнай каждой из чисел

Let's call the three numbers A, B, and C.

According to the given information:

1. A + B + C = 1000
2. A + B = 650
3. B + C = 550

To find the values of A, B, and C, we can solve these equations simultaneously using algebraic methods.

We'll start by solving equation 2 for A: A = 650 - B

Now substitute this value for A in equations 1 and 3: (650 - B) + B + C = 1000 650 + C = 1000 C = 1000 - 650 C = 350

Substitute the value of C in equation 3: B + 350 = 550 B = 550 - 350 B = 200

Now substitute the values of B and C in equation 1: A + 200 + 350 = 1000 A = 1000 - 550 A = 450

So, the three numbers are A = 450, B = 200, and C = 350.
