nvm i meant this

you could use subsitution here.

let y=7-x

substitute into the second equation then solve the quadratic that results

it has integer solutions as well, so don’t worry about complex radicals

[bold plover]

So when I get -y^{2}+7y-10=0

is y equal to 5 and 2 or -5 and -2

[elder idol]

well, solve the equation, and check with the original equation as well.

is -5-2=7?

[bold plover]

no that's -7

so its 5 and 2?

👍

does it make sense now?

okay, can i explain a really funny way of setting this up?

i just found it very intriguing

if you don’t mind, of course
