Which is the correct solution to the equation 2x + 4 = 10?

To solve the equation 2x + 4 = 10, the first step is to isolate the term containing x. This is done by subtracting 4 from both sides of the equation. This gives us:

2x + 4 - 4 = 10 - 4, which simplifies to 2x = 6.

Next, to solve for x, we divide both sides by 2:

2x / 2 = 6 / 2, leading to x = 3.

Therefore, the correct solution to the equation 2x + 4 = 10 is x = 3. This value satisfies the original equation when substituted back in, confirming its correctness.

Understanding how to systematically isolate variables and solve linear equations is crucial in algebra, and this example illustrates the process clearly by showing how to manipulate the equation step-by-step.
