$x=7$

Explanation:

$2(- 6x+9) = -66$

First distribute the 2 to $-6x and 9$

$-12x+18 = -66$

Then Subtract $18$ from both sides

$-12x= -84$

And lastly, divide by $-12$

$x = 7$

$x=7$

Explanation:

$1.$ First, distribute the $2$ into the $(-6x+9)$ by first multiplying the $2$ by $-6x$ and then by $9$ to get $-12x+18$

$-12x+18=-66$

$2.$ Then, since $18$ does not have an $x$ with it, you can subtract 18 from both sides of the equation, taking away the $18$ from the left side and subtracting $18$ from $-66$ as well.

This makes sure that both sides of the equals sign are equal. When you solve equations like this, always try to look for ways to get the $x$ term alone on one side. So, by doing this step, you have

$-12x=-84$

$3.$ Look for ways to isolate $x$ again. This is an easy one since $x$ is just multiplied by $-12$ . Divide both sides by $-12$ to get $x=7$ .

$(-12x)/(-12) = (-84)/(-12)$

$x=7$

I hope this was helpful! :)
