Answer 3

It looks like you've provided four equations with remainders (ост). These equations are in the form " ?÷4=y(ост x) ", where "?" is the unknown number we're trying to solve for, "y" is a known number, and "x" is the remainder when "?" is divided by 4.

To solve for the unknown number, we need to use the remainder theorem, which states that when a number is divided by a divisor, the remainder is the same as the remainder when the sum or difference of its digits is divided by the same divisor.

Let's apply this theorem to each equation:

• ?÷4=7(ост 1): The remainder is 1, so the sum or difference of the digits must also have a remainder of 1 when divided by 4. The only number that satisfies this condition is 13. Therefore, ? = 13.

• ?÷4=6(ост 3): The remainder is 3, so the sum or difference of the digits must also have a remainder of 3 when divided by 4. The only number that satisfies this condition is 27. Therefore, ? = 27.

• ?÷4=9(ост 2): The remainder is 2, so the sum or difference of the digits must also have a remainder of 2 when divided by 4. The only number that satisfies this condition is 38. Therefore, ? = 38.

• ?÷4=5(ост 3): The remainder is 3, so the sum or difference of the digits must also have a remainder of 3 when divided by 4. However, there are multiple numbers that satisfy this condition, such as 19, 23, 27, and so on. Without additional information or constraints, we cannot determine a unique solution for ? in this case.
