What is the solution to the equation 2x + 4 = 12?

To find the solution to the equation 2x + 4 = 12, we start by isolating the variable x. First, we can subtract 4 from both sides of the equation to eliminate the constant term on the left side:

2x + 4 - 4 = 12 - 4, which simplifies to 2x = 8.

Next, we need to solve for x by dividing both sides of the equation by 2:

2x / 2 = 8 / 2, which simplifies to x = 4.

Here, the value of x we derived from the calculations is 4. This means that when we substitute x with 4 in the original equation (2(4) + 4), we get:

2 * 4 + 4 = 8 + 4 = 12, confirming that the equation holds true.

Thus, the solution x = 4 satisfies the original equation, making it the correct answer.
