Question

Hey everyone I have a question on this equation 3x-y=4. is it okay to use the fomula y=mx+b in a reverse kind of way like this one b+mx=y
Ex: 3x-y=4
3x-4=y

is this way correct or not? Can you also tell me why?

Answer 1

They are both equal

Answer 2

It ends up the same

Answer 3

yes. you may use the formula in reverse:

as you can see, when you have 3x-y=4 and you add the y and subtract the 4 from both sides, you end up with 3x-4=y

Answer 4

you will just solve for y.
subtract the 3x and divide by -1.
It ends up the same.

Answer 5

I see, thank you.
