Given the following system of equations:

βˆ’4x + 8y = 16
2x + 4y = 8

what action was completed to create this new equivalent system of equations?

βˆ’2x + 4y = 8
2x + 4y = 8

multiply the second equation, 2x + 4y = 8, by βˆ’1.
multiply the first equation, βˆ’4x + 8y = 16, by βˆ’1.
divide the second equation, 2x + 4y = 8, by 2.
divide the first equation, βˆ’4x + 8y = 16, by 2.
