Question

Choose the correct first step(s) to solve the system using elimination.

4x + 7y = 6 and 6x + y = 2

Answer 1

Multiply 6x+y=2 by -7, but there are many choices possible. Is this multiple choice?

Answer 2

yes it is

Answer 3

Listing the choices would help figure it out.

Answer 4

sure here.7(6x + y = 2) → -42x - 7y = -14


4x + 7y = 6x + y


y = -6x + 20 → 4x + 7(-6x + 20) = 6


(4x + 7y) + (6x + y) = 8


(4x + 7y) - (6x + y) = 4

Answer 5

-42x-7y=-14

Answer 6

multiplying by -7

Answer 7

i thought that one also. between and third one

Answer 8

The third one wouldn't eliminate any variables though.

Answer 9

aha ok. i'll give you a medal when i find out if its correct or not :D
