Respuesta :
the answer is System 2 and system 3, because the second equation in system 3 is
obtained by adding the first equation in system 2 to two times the
second equation in system 2, i just took the test.
Answer:
system 2 and system 3 have the same solution.
Step-by-step explanation:
system 1:
[tex]4x-5y=2[/tex]
[tex]3x-y=4[/tex]
we'll solve the two equation by the method of elimintaion to get the value of x and y.
on solving we get [tex]x=\frac{18}{11} ,y=\frac{10}{11}[/tex].
system 2:
[tex]4x-5y=2\\10x-21y=10[/tex]
on solving the above two equation by the method of elimination we get the value of x and y.
on solving we get [tex]x=\frac{-4}{17},y=\frac{-10}{17}[/tex].
system 3:
[tex]4x-5y=2\\24x-47y=22[/tex]
on solving the above two equation by the method of elimination we get the value of x and y.
on solving we get [tex]x=\frac{-4}{17} ,y=\frac{-10}{17}[/tex].
system 4:
[tex]4x-5y=2\\10x+3y=15[/tex]
on solving the above two equation by the method of elimination we get the value of x and y.
on solving we get [tex]x=\frac{81}{62} ,y=\frac{20}{31}[/tex].
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.
