8th grade math

posted by .

I need to know how to work this math problem: 3n + (-7) -5n +1

  • 8th grade math -

    3n + (-7) -5n +1

    3n - 5n + 6

    -2n + 6

  • 8th grade math -

    Like Ms. Sue showed, you need to combine like terms.

    3n-5n=-2n
    -7+1=-6

    You cannot combine -2n and -6 so the answer would be -2n-6.



    -2n-6
