ok give me a second or longer, thanks

n + n + n + 6 = 81 * 2
3n + 6 = 162 - 6
3n = 156
n=156/2
n=78

this isn't right what am I doing wrong?

To start, you have 3n -- but you only have 2 test scores.

Your answer of 78 is correct for the first score. Add 6 to it for the other score.

78 + 84 = 162

162/2 = 81
