Final answer:
The solution to the system of equations is (0, -5).
Step-by-step explanation:
The solution to the system of equations can be found by substituting the known values of v and u' into the equation u =. From the given information, we have v = 0.500c and u' = -0.750c. By substituting these values into the equation u =, we get u = -1.500c. Therefore, the solution to the system of equations is (0, -5), which corresponds to option c).
