Question

What does 16=c+(-5) equal? And how do you get to that answer?

Answer 1

you take 16 and -5 and subtract them to get the answer which is 11

Answer 2

Actually the the answer would be 21 because the positive in front of the negative 5 doesn't really matter anymore so the problem now looks like c - 5 =16
+5. +5
C=21
-5+5 cancel out
16+5=21
