Me with this problem 9x-(2x+8)=. and show your work? i'll be giving brainilest!

So first, you want to open the parenthesis here.

So, to do that, first look at the symbol before the parenthesis.

In this case it's a -.

So when it's a -, reverse the symbol inside the parenthesis. (This is because if you don't you're subtracting 2x and then adding 8, when really you're subtracting both 2x and 8.)

So,

9x - 2x - 8

Or simplified,

7x - 8

9x - 2x + 8

7x + 8 is your answer

hope this helps
