Answer 1

Ответ:

1) (х + y) - (х - у)=х + y - х +у=2y

2) (m - n) - (m+n)=m - n - m-n=-2n

Answer 2

Exercise 1: (x + y) - (x - y)

To solve this exercise, we need to simplify the expression (x + y) - (x - y).

Expanding the brackets, we get: (x + y) - (x - y) = x + y - x + y

Combining like terms, we have: x - x + y + y = 2y

Therefore, the simplified expression is 2y.

Exercise 2: (m + n) - (m + n)

For this exercise, we have the expression (m + n) - (m + n).

Expanding the brackets, we get: (m + n) - (m + n) = m + n - m - n

Combining like terms, we have: m - m + n - n = 0

Therefore, the simplified expression is 0.
