Use the elimination method to solve the system of equations. Choose the correct ordered pair.

- x + y = - 3

3x + 2y = 9

A. (3,0)

B. (6,3)

C. (5,2)

D. (4,1)

A. (3, 0).

Step-by-step explanation:

- x + y = - 3

3x + 2y = 9 Multiply the first equation by - 2:

2x - 2y = 6 Adding the last 2 equations to eliminate y:

5x = 15

x = 3.

Substitute for x in the second equation:

3 (3) + 2y = 9

2y = 9 - 9 = 0

y = 0.

Answer is a

x=3+y

3 * (3+y) + 2y=9

9+3y+2y=9

y=0

x=3

(3; 0)
