7n + 4


7n – 4


3n + 4


3n – 12

Answer 1

Given:

Consider the given expression is:

`10n-(1)/(3)(9n-12)`

To find:

The simplified form of the given expression.

Solution:

We have,

`10n-(1)/(3)(9n-12)`

Using distributive property, it can be written as:

`=10n-(1)/(3)(9n)-(1)/(3)(-12)`

`=10n-3n+4`

`=7n+4`

Therefore, the correct option is A.
