The average of two quiz scores is 81. If one quiz score is six more than the other quiz score, what are the two quiz scores?

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