Math problem ALGEBRA?

Ive been studying inverse all night and this question has done my head in? It's algebra and I have to find 5(k+6) = -15

Whats n?

Comments

  • i think u need to make k as a so k+6=15/5

    k+6=3

    k=3-6

    k=-3

    thats the answer

  • no n in the equation so i assume u want to find k

    so expand first

    5k+30=-15

    so multiply through by 1/5

    so thats 5k*1/5+30*1/5=-15*1/5

    k+6=-3

    k=-3-6

    k=-9

  • No wonder it's doing your head in....there is no n!!

    Surely, you mean what's k??

    Well, k + 6 = -15/5

    => k + 6 = -3

    so, k = -9

    :)>

  • k = -9

    5 (k+6)=-15

    so divide both sides by 5

    (k+6)=-3 take away 6 from both sides

    k=-9

    so that means

    5(-9+6)=-15

    this statement is true

  • You ask "What is n?"

    But there is not an "n" in sight!

    5 ( n + 6 ) = - 15

    5n + 25 = - 15

    5n = - 40

    n = - 8

  • 5k + 30 = -15

    5k = -45

    k= -9
