Pls! 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.

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

Step-by-step explanation:

we have

----> first equation

----> second equation

Solve by elimination

Multiply the second equation by -2 both sides

---> equivalent second equation

Adds first equation and the equivalent second equation

Find the value of y

substitute the value of x in any of the equations

the solution of the system is the point (3,1)

35-60 students are taking math.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
