Can someone me with this and make the answer right and you
given the following system of equations:

2x + 6y = 12
4x + 3y = 15

which action creates an equivalent system that will eliminate one variable when they are combined?

multiply the second equation by −2 to get −8x − 6y = −30.
multiply the first equation by 2 to get 4x + 12y = 24.
multiply the second equation by −4 to get −16x − 12y = −60.
multiply the first equation by −4 to get −8x − 24y = −48.
