The solution to the system of equations is the point where the two lines intersect. Based on your description, the solid line given by the equation \( y = \frac{1}{2}x + 6 \) and the dotted line given by the equation \( y = 2x + 3 \) intersect at the point \( (2, 7) \).
Thus, the correct response is:
(2, 7)
