Question

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

Answer 1

Ответ:

-2m + 4n.

Пошаговое объяснение:

(m+n)-( 2 m + n)-(m - 4 n) =

m + n -2m - n - m + 4 n = -2m + 4n.

Answer 2

To simplify the expression (m+n)-(2m+n)-(m-4n), let's apply the distributive property and combine like terms:

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

Distribute the negative sign inside the second parentheses:

m + n - 2m - n - m + 4n

Combine like terms:

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

Simplify:

-2m + 4n

So the simplified expression is -2m + 4n.
