A.

3x – 2y = 9


3x + 2y = 14


B.

x – y = –2


4x – 3y = 11


C.

–2x – y = –13


x + 2y = –11


D.

2x – y = 7


2x + 7y = 31

Answer 1

5 is the x value and 3 is the y value

plug in 5 for x and 3 for y to see which of the options works.

Answer 2

its not b

Answer 3

true it is not b.

Answer 4

I don't know this one

Answer 5

A.
3x – 2y = 9
3x + 2y = 14

gives
3(5) – 2(3) = 9 ---> 15-6=9 ✓
3(5) + 2(3) = 14 ---> 15+6=14 X


C.
–2x – y = –13
x + 2y = –11

gives
-2(5) – (3) = 9 ---> -10-3=-13 ✓
(5) + 2(3) = -11 ---> 5+6=-11 X

D.
2x – y = 7
2x + 7y = 31

gives
2(5) –(3) = 7 ---> 10-3=7 ✓
2(5) + 7(3) = 31 ---> 10+21=31 ✓
