Question

What is 9 - (-8) = 20 and how did you get that answer?

Answer 1

Answer:

9 -( -8)= 9 + 8= 17 not 20

17 is the solution

Answer 2

Answer: No solution

Step-by-step explanation:

9-(-8)=20             given

9+8=20                the two negatives cancel out, making the eight positive

17=20                   this statement is not correct, so the answer is no solution

no solution

I'm not sure if there was supposed to be a variable in there somewhere, but I did my best to explain. Hope this helps!
