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

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

adryin · Answer

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
