Question

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

Which equation completes the system that is satisfied by the solution (3, 5)? (4 points)


x + 2y = 15

x + y = 15

x + y = 8

x − y = 2

Answer 1

The answer is x + y = 8

The coordinates are (3,5) where 3 is the x coordinate and 5 is the y coordinate.

If you substitute (3,5) into x + y = 8

you'll get get

3 + 5 = 8 which is true

Answer 2

the Answer is x + y = 8 because 3 + 5= 8
