nvm figured it out

mods pls delete

You basically isolate each variable and then solve for each variable algebraically

get it in reduced row echelon form

from there the solution should be trivial

1. Write it as a matrix.
2. Use gauss elimination or whatever you want to get a solution.
3. ???
4. Profit

It's not worth the time bruh

rref(matrix representation)

...

what do you want to evaluate? you just presented a function.

what is a matrix xDDd

Why do brainlets like post when they don't understand?

evaluate it then

you're being troled

why!!!

you allowed it to happen
this is all your fault
you could have prevented this
but you chose to be trolled

You got me to actually do the math opie
Glad to see I can still do basic ass linear algebra by hand

x=1
y=6
z=-6

I also have a fun question

1+1/2+1/4+1/8... etc. = (2x-1)/x

What's x?

Much faster to solve with algebra. Dont need to impress anyone here with fancy shit

Thats the number of parts in the series
