Question

N - 2n + 3n - m - 4n =​

Answer 1

n-2n+3n-m-4n = -n+3n-m-4n = 2n-m-4n = -2n-m = -2n-m

Answer 2

Ответ:

-2n-m

Answer 3

To simplify the expression N - 2n + 3n - m - 4n, you can combine the like terms (terms with the same variable) and perform the operations in order:

N - 2n + 3n - m - 4n

Combine the "n" terms:

N - (2n - 4n + 3n) - m

Perform the operations inside the parentheses:

N - (-3n) - m

Now, when you have a negative sign in front of parentheses, you can distribute the negative sign to all terms inside:

N + 3n - m

Finally, combine the "n" terms again:

N + (3n - n) - m

Simplify further:

N + 2n - m

So, the simplified expression is N + 2n - m.
