What function can be used to determine the cost of t-shirts from Timmy's T-shirts?

-2x + 6 -X

Step-by-step explanation:

7 - 1 = 6

So your equation would look like this:

-2x + 6 - X

Since you capitalized on the X I don't think you can do any further simplification.

Unless that was an accident :|
