Answer 1

Ответ: n- любое число

Пошаговое объяснение:

4n-n+4-9=n-5+2n

4n-n-n-2n=-5-4+9

0n=n

n- любое число

Answer 2

Let's solve the equation step by step:

4n - (n - 4) - 9 = n - (5 - 2n)

First, let's simplify the expressions within the parentheses:

4n - n + 4 - 9 = n - 5 + 2n

Combine like terms on both sides:

3n - 5 = 3n - 5

We can observe that the variable terms cancel out on both sides of the equation. The result is a true statement:

-5 = -5

This means that the equation is an identity, and any value of 'n' will satisfy it. In other words, the equation is true for all values of 'n'.
