Given the following system of equations: 3x + 5y = 30 x + 3y = 10 which action creates an equivalent system that will eliminate one variable when they are combined?

Hey just a heads up the answer is B

Step-by-step explanation:

I actually just did this exam on FLVS 4.03 Equivalent Systems

My answer from the test is found below.

Question 10 (Worth 1 points)

(04.03 LC)

Given the following system of equations:

3x + 5y = 30

x + 3y = 10

Which action creates an equivalent system that will eliminate one variable when they are combined?

Multiply the second equation by −1 to get −x − 3y = −10.

Multiply the second equation by −3 to get −3x − 9y = −30.

Multiply the first equation by −1 to get −3x − 5y = −30.

Multiply the first equation by −3 to get −9x − 15y = −90.
