Simplify 7m - 11n - n + 5m.
goblinko [34]

Answer:

The simplified form of the given expression is 12(m -n).

Step-by-step explanation:

The given expression is

7m - 11n - n + 5m

We need to simplify the given expression.

Rearrange the terms according to the variables.

7m+5m - 11n - n

On combining like terms, we get

(7m+5m)+( - 11n - n)

On simplification, we get

(12m)+( -12n)

12m -12n

Taking GCF common.

12(m -n)

Therefore the simplified form of the given expression is 12(m -n).
