Question

|7-y|=-2 Модуль 7-у равен -2.

Answer 1

Здесь нет решения. Модуль это расстояние, а расстояние не может быть отрицательным.

Answer 2

The equation |7-y|=-2 has no solution in the real number system. The absolute value (modulus) of any real number is always non-negative, which means it cannot be equal to a negative number like -2.

In mathematical terms, for any real number x, |x| ≥ 0, and |x| = 0 if and only if x = 0.

Since |7-y| is always non-negative, it can never be equal to -2. Therefore, there are no real values of y that satisfy the given equation.
