color(blue)(x=25/27

#### Explanation:

$- 3 \sqrt{3 x} = - 5$

Squaring both sides

${\left(- 3 \sqrt{3 x}\right)}^{2} = {\left(- 5\right)}^{2}$

$9 \cdot 3 x = 25$

$27 x = 25$

$x = \frac{25}{27}$

#### Explanation:

Let's start by dividing both sides by $- 3$ to get

$\sqrt{3 x} = \frac{5}{3}$

To get rid of the radical, we can square both sides to get

$3 x = \frac{25}{9}$

We can multiply both sides by $\frac{1}{3}$ to isolate $x$ to get

$x = \frac{25}{27}$

Hope this helps!
