The table below shows four systems of equations:

System 1 System 2 System 3 System 4

4x - 5y = 2

3x - y = 4 4x - 5y = 2

10x - 21y = 10 4x - 5y = 2

24x - 47y = 22 4x - 5y = 2

10x + 3y = 15

Which pair of systems will have the same solution?

System 1 and system 2, because the second equation in system 2 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 1 and system 2, because the second equation in system 2 is obtained by adding the first equation in system 1 to three 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 three times the second equation in system 2
