# How do you solve -\frac { x } { 4} = 27?

Mar 9, 2018

$x = - 108$

#### Explanation:

Our goal with these is to isolate the variable, in our case $x$. By doing that, we need to undo any operation being applied to it (more on this at the end of my answer).

Right now, $x$ is being divided by $4$, so we must multiply both sides by $4$. We get:

$- x = 108$

We can divide both sides by $- 1$ to get:

$x = - 108$
