Answer:

2(n+3) - 6 = 2n

Explanation:

Let n stand for lonnie's starting number.

Kristy asks to add 3 to the number. It will become (n+3)

Now he ask to multiply the sum by 2. It will become 2(n+3).

Finally, he ask to subtract 6. It will become 2(n+3) - 6

The expression is : 2(n+3) - 6.

We can simplify it as follows :

= 2n+6-6

= 2n

Hence, the required expression is 2n.
