3(n)-2(2n+2)=1/3(n+4)

help please,
show your work.

thank you!

  • Algebra 1 - ,

    If you meant

    3(n)-2(2n+2)=1/3 * (n+4)

    then just multiply by 3 and expand stuff out:

    9n-6(2n+2)= (n+4)
    9n-12n-12 = n + 4
    -4n = 16
    n = -4

    If you meant

    3(n)-2(2n+2)=1/(3(n+4))

    then things get a bit more interesting and there is no real solution.

  • Algebra 1 - ,

    3n - 4n -4 = 1/3(n+4)

    -n - 4 = 1/3 (n+4)
    multiply all parts by 3

    -3n -12 = n + 4
    -4n = 16
    n = -4
