Question

Line R is represented by the following equation:

x + y = 2

Which equation completes the system that is satisfied by the solution (1, 1)?


2x + y = 2
4x – 2y = 2
2x – 2y = 2
x + y = 4

Answer 1

all you need to do is plug in the x=1 and y=1 for all of them and see which words
example for the first 2(1)+(1)=2+1=3 but three is not 2
so does not work
continue like

Answer 2

that does not help me at all i don't get what you said
