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

Question

help please,
show your work.

thank you!

Answer 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.

Answer 2

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
