I NEED HELP WILL MARK BRAINLIST
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 βˆ’2 to get βˆ’8x βˆ’ 6y = βˆ’30.
Multiply the first equation by 2 to get 4x + 12y = 24.
Multiply the second equation by βˆ’4 to get βˆ’16x βˆ’ 12y = βˆ’60.
Multiply the first equation by βˆ’4 to get βˆ’8x βˆ’ 24y = βˆ’48.

Answer:

Multiply the second equation by βˆ’2 to get βˆ’8x βˆ’ 6y = βˆ’30.

Step-by-step explanation:

{2x + 6y = 12

{4x + 3y = 15

{2x + 6y = 12

{βˆ’8x βˆ’ 6y = βˆ’30 >> New Equation

* Doing this will give you additive inverses of βˆ’6y and 6y, which result in 0, so they are both ELIMINATED.
