\( 1 \leftarrow \begin{array}{l}\text { Solve for } x . \text { Check your solution. } \\ -15 x=-180 \\ x=\square\end{array} \)

To solve for \( x \), you need to isolate it. Start by dividing both sides of the equation by -15: \[ x = \frac{-180}{-15} = 12 \] Now, let’s check the solution by substituting \( x \) back into the original equation: \[ -15(12) = -180 \] Since both sides of the equation are equal, \( x = 12 \) is indeed the correct solution!
