The table below shows four systems of equations: system 1 system 2 system 3 system 4 4x − 5y = 2 3x − y = 8 4x − 5y = 2 13x − 8y = 4 4x − 5y = 2 13x − 8y = 26 4x − 5y = 2 10x + 3y = 15 which pair of systems will have the same solution? system 1 and system 3, because the second equation in system 3 is obtained by adding the first equation in system 1 to two times the second equation in system 1 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 system 2 and system 3, because the second equation in system 3 is obtained by adding the first equation in system 2 to three times the second equation in system 2 system 1 and system 3, because the second equation in system 3 is obtained by adding the first equation in system 1 to three times the second equation in system 1
