Help me with this problem 9x-(2x+8)=. And show your work? I'll be giving BRAINILEST!. Created by annietretyak. middle-school-us - mathematics-us

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 - 8Or simplified,7x - 8

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
