• 

Solve the system by elimination

4x + 8y = 20

-4x + 2y = -30

Write your answer as an ordered pair in the form (x,y)

Solve the system using the substitution method.

y = 7x

8x + y = 45

Write your answer as an ordered pair in the form (x,y).

Solve the system using the substitution method.

x = -4y + 1

8x + 9y = 54

Which ordered pair represents the solution?

• (9, -2)

• (-2, 7)

• (-3, 1)

Solve the system using the elimination method.

x - 8y = -3

4x + 8y = 28

Which ordered pair represents the solution?

• (0, 10)

• (-2, 7)

• (5, 1)
