Question 1009479: -9+(2-x)+8x
The first - is a negative i was unsure how to make it where it looks like a negative andd not a minus.
So negative nine plus (two minus x) plus 8
~ how my mom was showing me (don't know if she is right please help!)
You do whats in the () first so
-9+(2-x)+8×
-9+(2x)+8x
-9+2x+8x
Do we do the xs first?
2x+8x=10x
-9+10x= 1x
Im so confused
Thank you in advance

You can put this solution on YOUR website!

remember:
The Order of Operations: PEMDAS
-Do things in Parentheses First.
-Exponents (Powers, Roots) before Multiply, Divide, Add or Subtract.
-Multiply or Divide before you Add or Subtract.
-Otherwise just go left to right.
-9%2B%282-x%29%2B8x....you need first to eliminate parentheses; if we have plus sign in front of parentheses, just disregard them, nothing will change
-9%2B2-x%2B8x ....now combine like terms
%282-9%29%2B%288x-x%29....if you need to subtract greater number from smaller number, just subtract smaller from greater number and put minus sign in front of difference:
so, 2-9 is same as -%289-2%29=-7
-7%2B7x...you can swap the places
7x-7
