    Thank you.

    I showed you how to do the first three steps in your last post.

    Now it's your turn. I'll be glad to check your answer.

    ok give me a second or longer, thanks

  • algebra - ,

    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
