Answer 2

Option C is correct.

The answer for the given expression is 0.

Explanation:

Given the statement: Two times the difference of one-third of a number and three. and also variable given is 9.

Let x be the variable or number.

"One-third of a number" means
`(1)/(3)x`

Also, "difference of one third of a number and three " means
`(1)/(3)x-3`

Now, "Two times the difference of one-third of a number and three" means
`2 * ((1)/(3) x -3)`

Then, the expression for the given statement :
`2 * ((1)/(3) x -3)`

Substitute the value of x =9 in above expression we have;

`2 * ((1)/(3)(9) -3)` =
`2 * (3 -3)` =
`2 * (0)` = 0

therefore, the answer for the given expression is, 0
