A system of equations has infinitely many solutions. If 2y – 4x = 6 is one of the equations, which could be the other equation?

y = 2x + 6
y = 4x + 6
–y = –2x – 3
–y = –4x + 6

Answer :

Answer:

-y = 2x-3

Step-by-step explanation:

This is because as last step if 2y is divided by 2 then we would apply same each side to make -4x-6 become -2x -3

The other equation in the system could be (c) -y = -2x - 3

How to determine the other equation?

The equation is given as:

2y - 4x = 6

Divide through by 2

y - 2x = 3

Add 2x to both sides

y = 2x + 3

Multiply through by -1

-y = -2x - 3

Hence, the other equation could be (c) -y = -2x - 3
