Answer 2

Ответ:

Пошаговое объяснение:

5n-10-6n+18-6n+27=0

5n-6n-6n=10-18-27

-7n= 35 /-7

n=5

Answer 3

To simplify the expression 5(n-2)-6(n+3)-3(2n-9), we can distribute the coefficients and then combine like terms. Let's break it down step by step:

1. Distribute the coefficients: 5(n-2) = 5n - 10 -6(n+3) = -6n - 18 -3(2n-9) = -6n + 27

2. Combine like terms: (5n - 10) - (6n + 18) - (6n - 27)

   Removing the parentheses: 5n - 10 - 6n - 18 - 6n + 27

3. Combine like terms: (5n - 6n - 6n) + (-10 - 18 + 27)

   Simplifying the terms within each grouping: -7n - 1

Therefore, the simplified form of the expression 5(n-2)-6(n+3)-3(2n-9) is -7n - 1.
