Question

8АА - А2А = 330 8АА и А2А -трехзначные числа Найдите значение суммы А+А=?

Answer 1

Ответ:

10

Пошаговое объяснение:

прибавляем 20 к обеим частям равенства

8АА-А2А+20=330+20

8АА-А0А=350

получаем А равное 5 (т.к. А-0=5; изначальное равенство 855-525=330)

5+5=10

Answer 2

To find the value of A + A, we need to first solve the equation:

8AA - A2A = 330

Let's break down the numbers:

8AA (a three-digit number) - A2A (also a three-digit number) = 330

To make the subtraction easier, let's align the digits:

8A A

• A 2 A

From the rightmost column, we have A - A = 0. So, there is no carryover to the middle column.

Moving to the middle column, we have A - 2 = 3. This implies that A must be equal to 5 (since 5 - 2 = 3).

Therefore, the value of A + A is 5 + 5 = 10.
