Question 1152209
  
My equation is x+5-7x-2. Combined like terms, I get -6x+3. My math book says the answer is -6x+7. What am I doing wrong here because I don't get how that negative two ends up being positive to make 7.
============================
Problem: "Subtract 7x-2 from x + 5"

    x + 5
- (7x - 2)
------------------
   x + 5
 -7x + 2
======================= Add
 -6x + 7
