3x + 2y + 16x^3z + 6y =

ANSWER: 19x + 8y + 3z

  • math -

    again, incorrect

    when you add/subtract terms they must be "like"
    the variables and exponents do not change.

    3x + 2y + 16x^3z + 6y
    = 3x + 8y + 16x^3z

    (the only terms that were "like" were the y terms )

  • math -

    If the problem has no typos, it can reduce to:

    16x^3z + 8y + 3x

  • math -

    the question is i wrote it wrong
    3x + 2y + 16x + 3z + 6y =

  • math -

    So what is your answer?

    I see three kind of terms, x's , y's and z's

  • math -

    19x + 8y + 3z

  • math -

    Right.
