**franklin**, Friday, October 29, 2010 at 9:29pmn + 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?

**Ms. Sue**, Friday, October 29, 2010 at 9:35pmTo 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
