Solve the Linear Equation: Finding X in -6x = 18

To solve the equation $-6x = 18$, we need to isolate the variable $x$.

Our equation is:

$-6x = 18$

The variable $x$ is multiplied by $-6$. To undo this operation and solve for $x$, we divide both sides of the equation by $-6$. This will isolate $x$ on one side of the equation:

$\frac{-6x}{-6} = \frac{18}{-6}$

Simplifying both sides, we find:

$x = -3$

Thus, the solution to the equation $-6x = 18$ is $x = -3$.

Therefore, the correct answer is $x = -3$.
