The given linear equation is already in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. Therefore, to solve for x, we need to isolate it on one side of the equation. In options A, B, and C, the variable x is not isolated and therefore, those options are incorrect. Option D isolates x by subtracting 4 from both sides and then dividing both sides by 2. This results in x = (y - 4)/2, making it the correct answer.
