Is this the right answer? 42+x-3(x-2)+11
42+8-3(8-2)+11
47×6+11
282+11
293

  • math -

    No.
    As I understand your problem, x is an unknown.

    42+x-3(x-2)+11

    42 + x - 3x + 6 + 11

    42 + 17 - 2x

    59 - 2x

  • math -

    No x is 8

  • math -

    In that case, things are still a bit off:

    42+8-3(8-2)+11
    42+8-3(6)+11
    42+8-18+11
    50-18+11
    32+11
    43

    multiplication comes before addition
