Question

Match the systems of equations to their solutions.

2x + y = 12
x = 9 − 2y
x + 2y = 9
2x + 4y = 20
x + 3y = 16
2x − y = 11
y = 11 − 2x
4x − 3y = -13
y = 10 + x
-3x + 3y = 30
2x + y = 11
x − 2y = -7
x = 2, y = 7
arrowRight
x = 5, y = 2
arrowRight
x = 3, y = 5
arrowRight
x = 7, y = 3
arrowRight

Answer 1

9 − 2y

x + 2y = 9

2x + 4y = 20

x + 3y = 16

2x − y = 11

y = 11 − 2x

4x − 3y = -13

y = 10 + x

-3x + 3y = 30

2x + y = 11

x − 2y = -7

x = 2, y = 7

arrowRight

x = 5, y = 2

arrowRight

x = 3, y = 5

arrowRight

x = 7, y = 3

arrowRight
