im stuck in this exercise

[tex]9m+2 \\ -(3m+8) \\ - - - - - \\ 6m - 6 \\ - - - - - [/tex]
Solution :-
[tex]9m + 2 - (3m + 8) \\ 9m + 2 - 3m - 8 \\ m(9 - 3) + (2 - 8) \\ 6m - 6[/tex]
Answer:
6m - 6
Step-by-step explanation:
9m + 2 - (3m + 8) = 9m + 2 -3m -8
= 9m - 3m + 2 - 8
= 6m - 6
when you open the brackets, -(+3m) = -3m because when a positive sign times a negative sign, you get a negative sign. so, same thing for -(+8) = -8
