What is the value of x in the equation 2x + 4 = 14?

The correct answer is: 5

To solve this equation, we need to isolate the variable x on one side of the equal sign. To do this, we first subtract 4 from both sides, resulting in 2x = 10. Then, we divide both sides by the coefficient of x, which is 2, and we are left with x = 5. The other options may seem like possible solutions, but they do not correctly solve the equation. Option B, 10, is the value for 2 times x plus 4, not for just 2x. Option C, 6, and D, 8, do not result in a correct solution when plugged into the equation. Therefore, the only correct answer is A, 5.
