Answer:
system 2 and system 3 have the same solution.
Step-by-step explanation:
system 1:
we'll solve the two equation by the method of elimintaion to get the value of x and y.
on solving we get .
system 2:
on solving the above two equation by the method of elimination we get the value of x and y.
on solving we get .
system 3:
on solving the above two equation by the method of elimination we get the value of x and y.
on solving we get .
system 4:
on solving the above two equation by the method of elimination we get the value of x and y.
on solving we get .
on looking for the solution of all the four system we see that system 2 and system 3 have the same value for x and y.
Hence, system 2 and system 3 have the same solution.
