is this right? n-25=-18 n-25+25=-18+25 n=-7

jimthompson5910 (jim_thompson5910):

the left side is correct, but the right side should be -18+25 25 - 18 7 So n = 7

jimthompson5910 (jim_thompson5910):

you don't have to flip the terms, but it helps to see that you're really subtracting here

my is answer is correct?

jimthompson5910 (jim_thompson5910):

no, unfortunately it's incorrect as it's not n = -7 It's actually n = 7
