This is what I have:

1/3x+5=-4
1/3x+5-5=-4-5
1/3x=-9
1/3x=-27/3
?

This is pretty much what I did.

--Be more organized please .

Solve for x :
\(\displaystyle \frac{1}{3x} + 5 = -4\)

\(\displaystyle \frac{1}{3x}=-9\)

\(\displaystyle 1=-27x\)

\(\displaystyle x=\frac{-1}{27}\)

x=-27... but i don't know the steps

I think you're missing something .

this is the problem: 1/3(x)+5=-4
x=-27

I need to know step by step how to get -27. Thank you for helping!

\(\displaystyle \frac{1}{3}\cdot x \, + \, 5 \, = \, -4\)

\(\displaystyle \frac{1}{3}\cdot x \, = \, -4\, - \, 5 \,\)

\(\displaystyle \frac{x}{3} \, = \, -9\)

multiply both sides by 3

\(\displaystyle \frac{x}{3} \cdot 3 \, = \, -9 \cdot 3\)

\(\displaystyle x \, = \, -27\)

You see the difference to what you've typed at the first time ... The x is for the numerator not for the denomenator
