Question

The table below shows four systems of equations:

Answer 1

4x − 5y = 2
3x − y = 8 
x= 38/11
y=26/11

4x-5y=2
3x − 8y = 4 
x= -4/17
y=-10/17

4x - 5y =2
13x − 8y = 26 
x= 38/11
y=26/11

4x-5y=2
10x + 3y = 15
x= 81/62
y=20/31

Therefore, the correct answer is the last option.

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.
