5
7
12

Answer 1

Your answer is 7,

Known:n=12

So 12/3

First, we need to simplify 12/3

To simplify this, all we need to do is divide 12 by 3

12÷3=4

3 goes into 12 4 times.

So now our eqation is

9+4-6

9+4 is 13

13-6 is 7

Hope this helps

Answer 2

`9 + (n)/(3) - 6 = 7`

Explanation:

Given

`9 + (n)/(3) - 6`

Required

Evaluate when n = 12

Substitute 12 for n in
`9 + (n)/(3) - 6`

`9 + (n)/(3) - 6 = 9 + (12)/(3) - 6`

Simplify the fraction

`9 + (n)/(3) - 6 = 9 + 4 - 6`

`9 + (n)/(3) - 6 = 7`
