help?

[clever oxide]

No 27 is what I need help in.

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

well
assume the first digit is a and the second b

and write equations for it

[clever oxide]

I did this much

@upper halo

[upper halo]

so for the case where x-y=3 it doesn’t work

so what if y-x=3

[clever oxide]

x-y is

And According it the answer doesn't come

@gaunt cypress I need help sir.

[upper halo]

wdym

it just says one digit is 3 more than the other

what’s stopping y from being 3 more

[clever oxide]

In this there is 2 ways to solve the question both are correct... But only way gives the answer correct does that make sense?

[upper halo]

welll if you have -3 and -6 that’s clearly incorrect

[clever oxide]

Yes

What to do

[upper halo]

y-x=3

…

I just did that and got the answer

[clever oxide]

But this way should also be correct...

Why isn't it correct

Then I can't get it

[upper halo]

no no

so if x-y=3 we’re saying that in our number

the first digit is greater

but the first digit can also be smaller

and actually it makes less sense if the first digit is greater since the first number is multiplied by 7 and the second 4

so the first digit has to be smaller

[clever oxide]

Ok kinda get it

Thank you @upper halo
