Line Q is represented by the following equation: 2x + y = 11

Which equation completes the system that is satisfied by the solution (3, 5)?
x + 2y = 15
x + y = 15
x + y = 8
x − y = 2

Answer 1

Plug in x and y into the available choices.
3+2(5)=13 not 15
3+5=8 not 15
3-5 p=-2 not 2
The only logical answer is C

Answer 2

Answer:

C  (1, 1) is the solution to line K but not to line J..
