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.
