Which of the following best describes the first step in solving the system below using elimination?
2x - 4y = 9
x+3 = -4y
A. solve the second equation for X
B. rearrange the second equation to read x+4y = -3
C. rearrange the second equation to read x + 4y =
D. add the equations together

Respuesta :

Answer:

B

Step-by-step explanation:

Answer:

The answer is: to rearrange the second equation by adding "4y" to both sides and subtract 3 from both sides so it reads: x + 4y = -3

Please notice that two options that you presented read kind of similar (so there may be a typo). Make sure that you select the options you were given that aligns to the answer shown above.

Step-by-step explanation:

In order to solve a system of equations via the elimination method, the first step is to write both equations in standard form. That is, with the terms containing variables on the left, (and alphabetically ordered by they variables), and the pure numerical term on the right hand side of the equal sign.

In our case, since the first equation is already written in standard form, to rearrange the second equation by adding "4y" to both sides and subtract 3 from both sides so it reads: x + 4y = -3
