Looking at the second equation, the coefficient of the variable x is -2.
Since the coefficient of x in the first equation is 4, we would need a coefficient of -4 in the second equation in order to cancel them.
We already have -2, so to have -4, we need to multiply the second equation by 2.
The coefficient of y is 3 and in the second equation is -1, so we would need to multiply the equation by 1/3 in order to cancel them.
So the correct option is the third one.
