• y

• both

• neither

What is the resulting combined equation to the following system of equations when using the Elimination Method?

5x - 4y = 11

5x + 4y = 4

• 8y = 15

• 10y = 15

• 10x = 15

• 25x = 15

• (1,5)

• (6,2)

• (-2,6)

• (4,6)

 4x + 8y = 20
-4x + 2y = -30

• (-7,1)

• (2,-5)

• (-2,5)
