Answer:
-8(-7r-7)+8=-272
We move all terms to the left:
-8(-7r-7)+8-(-272)=0
We add all the numbers together, and all the variables
-8(-7r-7)+280=0
We multiply parentheses
56r+56+280=0
We add all the numbers together, and all the variables
56r+336=0
We move all terms containing r to the left, all other terms to the right
56r=-336
r=-336/56
r=-6
