Q:
# I NEED HELP WILL MARK BRAINLISTGiven the following system of equations:2x + 6y = 124x + 3y = 15Which 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:{2x + 6y = 12{4x + 3y = 15{2x + 6y = 12{−8x − 6y = −30 >> New Equation* Doing this will give you additive inverses of −6y and 6y, which result in 0, so they are both ELIMINATED.** [3, 1] is your solution.I am joyous to assist you anytime.
