I'm trying to do the following operation with my TI-Nspire CAS; I have:
x=a+b
y=a-c
I'd like to get:
y=x-b-c
Thank you so much for your time.

Se := instead of =. – soegaard Apr 01 '18 at 08:52

Hello @soegaard, I tryed x:=a+b and y=a-c, and x:=a+b and y:=a-c, but both solutions don't work; the result is always y=a-c instead of y=x-b-c. Thank you for your help and happy Easter. – Gennaro Arguzzi Apr 01 '18 at 09:37

How about. Solve( x=a+b and y=a-c , {y,x,b}) – soegaard Apr 01 '18 at 09:43

I get the result: x=a+c1 and y=a-c and b=c1. Maybe TI-Nspire CAS can't do what I want. – Gennaro Arguzzi Apr 01 '18 at 09:47

Something like this:
i1:=solve(x=a+b,a)
y:=a-c|i1
