Q:

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.

Accepted Solution

A:
Answer:Multiply the second equation by −2 to get −8x − 6y = −30.Step-by-step explanation:we have ----> first equation ----> second equationSolve by eliminationMultiply the second equation by -2 both sides ---> equivalent second equationAdds first equation and the equivalent second equationFind the value of ysubstitute the value of x in any of the equationthe solution of the system is the point (3,1)
