Solve.


-1/4y = 16

Answer 1

-64

Answer 2

idk

Answer 3

First multiply -1 on both sides of the equation since you are dividing -1 in the orignal problem

\(\Large \frac{-1}{4y}~=~16\)

\(\Large -1 \times \frac{-1}{4y}~=~16\times -1\)

\(\Large 4y~=~16\times -1\)

So what is 16 x -1?

Answer 4

-16

Answer 5

Um...@sammixboo you made a mistake

Answer 6

\(\large -1\times\frac{-1}{4y}\neq 4y\)

Answer 7

dang again sammi tisk tisk tisk

Answer 8

Just do this:
\(\large -\frac{1}{4}y=16\rightarrow -4(-\frac{1}{4}y)=16(-4)\rightarrow y = -64\)

Answer 9

Thanks :)

Answer 10

Good now we plug in -16 where 16 x -1 was

\(\Large 4y~=~-16\)

Now we must multiply 4 on both sides og the equation since we are dividing

\(\Large 4y \times 4~=~-16\times4\)

\(\Large y=~-64\)

Answer 11

Oh i see what you did there i didnt know you could do it like that

Answer 12

Strangely enough, although you made several mistakes @sammixboo , you still "got" the right answer.

Answer 13

You can't @matlee . Not really.

Answer 14

I just skipped steps

It cancels each other out and all

Answer 15

No she multiplied by 1 in the first place

Answer 16

It's how I learned it

Answer 17

then she did the 4 after

Answer 18

although it was suppose to be 1/4 first then the 4

Answer 19

I am not sure how it works, but it always turn out as the right answer. I never really got it

Answer 20

It defies the rules of algebra....

Answer 21

I think you made some mistakes, but you fixed it in your head, without showing every single step on here, so it came out okay. :)
Weird, but if it works for you, then whatever. xD
@sammixboo

Answer 22

But I know your way is a right way I just never learned it like that

Answer 23

Well Study no offense but at the end she was right and it seem to me like common sense so....

Answer 24

Im out to the next question

Answer 25

:) I never been good at explaining math DX But my teacher just showed me another way to explain somewhat how I got my answers and that is how I have been doing it since I was 11

Answer 26

@Here_to_Help15 It's not common sense. Because...
\(\large 4x\times 4=-16\times4\rightarrow16x=-64\)

Answer 27

I think it is just some kind of cheat to skip some steps, but still get the same answer

Answer 28

(replace the x's with y's sorry)

Answer 29

I know. It is that the 4x cancels out the times 4

Answer 30

Like I said, if you get the right answer, then by all means do it. :) Just cause I don't understand the process doesn't mean that it's a wrong process. Maybe one day you can teach me your method @sammixboo \(\large\ddot\smile\)

Answer 31

My teacher explained a loooong explanation about how it works when I was younger, but I never really payed attention to that explanation, but it has always gotten me the right answer :)

Answer 32

Dont worry guys ill call my math teacher

Answer 33

:)
