I NEED HELP
Match the systems of equations to their solutions.
x = 2, y = 7 - - ->
x = 5, y = 2 - - ->
x = 3, y = 5 - - ->
x = 7, y = 3 - - ->
Choices:
1 . 2x + y = 12
x = 9 โ 2y
2.
x + 2y = 9
2x + 4y = 20
3.
x + 3y = 16
2x - y = 11
4 y = 11 โ 2x
4x โ 3y = -13
5. y = 10 + x
-3x + 3y = 30
6. 2x + y = 11
x - 2y = -7
