7x - 3y = 4 2x - 4y = 1 Which of the following system of equations is not equal to the system of equations shown above? 28x - 12y = 16 and -6x + 12y = -3 14x - 6y = 4 and -14x + 28y = 1 -28x + 12y = -16 and 28x - 56y = 14

OpenStudy (adryin):

I think the second equation is not equal to the systems of equations above.

OpenStudy (kayders1997):

Okay you have to think about what you multiply by from the original function to the new function for each answer choice

OpenStudy (adryin):

And doing that on the second part of the second choice, 1 should've been multiplied by -7 being 14x - 6y = 4 and -14x + 28y = -7
