To solve the equation $2x + 6 = -4x - 12$, follow these steps:

1. Combine like terms involving $x$: $2x + 4x + 6 = -12$ $6x + 6 = -12$

2. Isolate the term with $x$ by subtracting 6 from both sides: $6x = -12 - 6$ $6x = -18$

3. Solve for $x$ by dividing both sides by 6: $x = \frac{-18}{6}$ $x = -3$

So, the solution is $x = -3$.
