Question

HELP FOR A MEDAL PLEASE

Answer 1

A: 6x - 3y = -4
B: -4x - y = 5
To solve this system of equations by elimination, what could you multiply each equation by to cancel out the y-variable?
A) Multiply A by 2 and B by 3
B) Multiply A by 1 and B by -3
C) Multiply A by 5 and B by -4
D) Multiply A by 3 and B by -2

Answer 2

I have no idea where to start

Answer 3

eliminating is to cancile out one part of the equation

Answer 4

B seems very Nice, why not test it out?

Answer 5

dont give out answer like that @latinC

Answer 6

lol hmmmm lets test B out XD

Answer 7

? what answer? Im just saying lets test B out

Answer 8

have you ever think that she want to learn

Answer 9

lol nawww who likes learning

Answer 10

thats why you test the answer for proof, math is all about proof. that is why the back of every math textbook has the answers

Answer 11

just go way guys

Answer 12

I would have to agree. Answer one question now is not as valuable as answer many later due to understanding what to do.

Answer 13

No! it is like when you get your math test back and you see all the right answers, you can either find out how to get the right answer or throw the test in the garbage

Answer 14

so lest eliminate the Y

Answer 15

It is okay if I know the answer but @12man yes you are correct I would like to know how you got that answer, so that if this question comes up again or something similar to it I know how to do it.

Answer 16

Using replacement and test works for multiple choice speed.
Open answer requires understanding the method.

Answer 17

bye guys

Answer 18

Im a Y in this equation:(

Answer 19

A: 6x - 3y = -4 --> by 1 --> 6x - 3y = -4

B: -4x - y = 5 --> By -3 --> 12x +3y = 12
--------------
18x + 0 = 8 y-variable eliminator; can solve for x.

Which option multiplies every member of equation A by 1 AND

multiplies every member of equation B by -3 ?
