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

we have

1) systems of equations 1

2x + y = 12

x = 9 − 2y

using a graph tool

see the attached figure

the solution is the point > (5,2)

2) systems of equations 2

x + 2y = 9

2x + 4y = 20

using a graph tool

see the attached figure

the solution is the point > has no solution the two lines are parallel

3) systems of equations 3

x + 3y = 16

2x − y = 11

using a graph tool

see the attached figure

the solution is the point > (7,3)

4) systems of equations 4

y = 11 − 2x

4x − 3y = -13

using a graph tool

see the attached figure

the solution is the point > (2,7)

5) systems of equations 5

y = 10 + x > multiplying by 3> 3y=30+3x> -3x + 3y = 30

-3x + 3y = 30

equation 1 and equation 2 are equals> the system has no solution

6) systems of equations 6

2x + y = 11

x − 2y = -7

using a graph tool

see the attached figure

the solution is the point > (3,5)
