All you do is separate the bracket and multiple everything inside the bracket by the number to its let.
That is 7s - 42 -2
Now do -42 - 2
And you get 7s - 44
So that your answer.
The answer should be 7s + -44 or 7s - 44
7(s - 6) - 2 > distribute the 7 to both the s and -6
7s - 42 - 2
7s - 44
Hope this helps!
