Final answer:
The given equations have no solution.
Step-by-step explanation:
The given equations are y = 3x + 6 and y = 3x - 7. To find the number of solutions, we need to compare the slopes of the two equations. Both equations have the same slope, which is 3, meaning that the lines are parallel and will never intersect. Therefore, the two equations have no solution.
