`1/3x+5 =-4`

Multiply `1/3 ` by `x` to get `x/3`

`x/3 +5=-4`

In order to get `x` alone to solve for it, subtract `5` from both sides of the equation.

`x/3 = -5-4`

`x/3 =-9`

Next, multiply both sides of the equation by `3` .

`3 (x/3) = -9(3)`

` x = -27`

Check the solution by inserting the value of x into the original equation.

`1/3(-27) +5 = -4`

`-9+5=-4`

`` `-4=-4`  check

x= -27
