It's asking us to write down the set of solutions to those equations (viewing them as an equation in the mentioned number of variables).View attachment 33851
Can someone please help explain what this question is asking? I missed some info and have no idea how to go about solving this, thanks
Also another quick one, I was wondering how to format an answer for this :

For two variables:
at the moment i have { (x1,x2) in R2 ; x1= 4-2*x2 , x2 = (4-x1)/2
edit:
i suppose this could also be written as {( M , (4-M)/2) in R2 ; M in R } ??
