noted: task (8,4) in the above set of tasks is changed to (0,8,4,4)

please answer the question conclude with calculation

Real time system = A system consists of three periodic tasks: T = {(8,4), (10, 2), (12,3)}. The parameters of task (8,4) in the above set of tasks is changed to (0,8,4,4). How will this change affect the schedulability of the set of tasks using the EDF algorithm? Be sure to conclude your calculations
