Question

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

3x − 2y = 1
4x − 5y = 2

3x − 8y = 4
4x − 5y = 2

10x − 9y = 4


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 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

Answer 1

System 2 and system 4, because the second equation in system 4 is obtained by adding the first equation in system 2 to two times the second equation in system 2
System 2 and system 4, because the second equation in system 4 is obtained by adding the first equation in system 2 to three times the second equation in system 2

Answer 2

its C or
D @iGreen.

Answer 3

Answer 4

Um..I think the question is messed up..two of the equations are by themselves.

Answer 5

okay so look move each one up so the one by itself goes with 3x-y=8 and so on get it?

Answer 6

Okay.

Answer 7

its C or D i graphed them on desmos

Answer 8

Yep, it's either C or D..hold on.

Answer 9

I think it's C..

Answer 10

Correct Answer: C) System 2 and system 4, because the second equation in system 4 is obtained by adding the first equation in system 2 to two times the second equation in system 2
