What is the solution to the equation 4x + 12 = 0?

-1
-2
-3
-4

The correct answer is: -3

To solve the equation 4x + 12 = 0, the goal is to isolate the variable x. Start by subtracting 12 from both sides of the equation. This gives: 4x + 12 - 12 = 0 - 12, which simplifies to: 4x = -12. Next, to find the value of x, divide both sides of the equation by 4: 4x / 4 = -12 / 4. This results in: x = -3. Therefore, the solution to the equation is -3. This value satisfies the original equation when substituted back, proving it is indeed the correct answer.
