Given the following system of equations:
−4x + 8y = 16
2x + 4y = 8
what action was completed to create this new equivalent system of equations?
−2x + 4y = 8
2x + 4y = 8
multiply the second equation, 2x + 4y = 8, by −1.
multiply the first equation, −4x + 8y = 16, by −1.
divide the second equation, 2x + 4y = 8, by 2.
divide the first equation, −4x + 8y = 16, by 2.
