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).

Thankyou , I assume in three variables it would follow the same way e.g {(x1,x2,x3) in R3: x1 = 5/2 }

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 } ??
