What is the value of x if 2x + 8 = 20?

4 6 8 10

Correct Answer:

Explanation:

To find the value of \( x \) in the equation \( 2x + 8 = 20 \), we start by isolating the term with \( x \). First, subtract 8 from both sides of the equation: \[ 2x + 8 - 8 = 20 - 8 \] This simplifies to: \[ 2x = 12 \] Next, to solve for \( x \), we divide both sides by 2: \[ x = \frac{12}{2} \] This results in: \[ x = 6 \] Thus, the correct value of \( x \) is 6. This value is determined by systematically breaking down the equation step by step. The other options do not satisfy the original equation when substituted back in, as they do not equate to the result needed to maintain the equality. Therefore, 6 is the only solution that resolves the equation correctly.
