Answer:


\huge\boxed{x=7}

Explanation:

In order to solve for x, our goal is to isolate it on one side of the equation. We can do this by reversing the equation.

Let's apply the distributive property on the left side:


(3 \cdot x) + (3 \cdot -10) = -9\\\\3x-30=-9

Add 30 to both sides:


3x - 30 + 30 = -9 + 30\\\\3x = 21

Divide both sides by 3:


3x / 3 = 21 / 3\\\\x = 7

So x = 7.

Hope this helped!
