Answer:
14x-6y=4 and 14x-28y=1
Step-by-step explanation:
we have
7x-3y=4 ----> equation A
2x-4y=1 ----> equation B
Multiply the equation A by 2 both sides
2*(7x-3y)=4*2
14x-6y=8
Multiply the equation B by 7 both sides
7*(2x-4y)=1*7
14x-28y=7
therefore
The system of equations that is not equal to the system of equations above is
14x-6y=4 and 14x-28y=1
