Best ResponseYou've already chosen the best response.1The table below shows four systems of equations: System 1 System 2 System 3 System 4 4x − 5y = 2 3x − y = 8 4x − 5y = 2 10x − 7y = 18 4x − 5y = 2 3x − 8y = 4 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

Best ResponseYou've already chosen the best response.1Look at choice A. Choice A tells you that the second equation of the second system is 2 times the second equation of the first system added to the first equation of the first system. If this is true, the equations are the same equation and the solutions will be the same. All you need to do is see if this is true. Multiply the second eq. of system 1 by 2. Then add it to the first eq. of system 1. What do you get?

Best ResponseYou've already chosen the best response.1Here is eq. 2 of system 1: 3x − y = 8 Multiply both sides of the equation by 2. What do you get?

Best ResponseYou've already chosen the best response.1Multiply both sides by 2: 2(3x − y) = 2(8) What do you get?

Best ResponseYou've already chosen the best response.1Great. Now add it to the first eq. of system 1. 4x  5y = 2 (+) 6x  2y =16  What do you get?

Best ResponseYou've already chosen the best response.1Check the +7y. Notice you are adding 5y and 2y. What is 5y + (2y) = ?

Best ResponseYou've already chosen the best response.15y + (2y) = 5y  2y = 7y Correct.

Best ResponseYou've already chosen the best response.1The equation is: 10x  7y = 18 Now compare this new equation with the second eq. of system, 2.

Best ResponseYou've already chosen the best response.1ok so what would i do? can you walk me through with it? @mathstudent55

Best ResponseYou've already chosen the best response.1The equation you got by doing what choice A tells you is exactly the second eq. of system 2. That means the answer is choice A. The first and second systems have the same answer.
