# How do you solve 3x + 18= - 18?

Mar 6, 2018

Isolate $x$ and solve to get $- 12$.

#### Explanation:

In order to solve for $x$, we want to get $x$ alone. In this case, we can subtract 18 from both sides in order to get the $3 x$ alone:
$3 x = - 36$

Now to isolate $x$, we divide both sides by 3:
$x = - 12$

$x = - 12$

#### Explanation:

$3 x + 18 = - 18$

Subtract $18$ from both sides, since you wanna isolate the $x$, which gets you

$3 x = - 36$

Divide both sides by $3$ to get the value for one $x$.

$x = - 12$

$x = - 12$

#### Explanation:

To get our constants on one side, we can subtract $18$ from both sides. We now have the equation

$3 x = - 36$

Lastly, we can divide both sides by $3$ to get

$x = - 12$

Hope this helps!
