Question: Parametric solution

In manual solution is no problem, but i am interest to compute it with any software such maple since i am not familiar, How to find solution in term of parametric equation a(r), b(r), c(r) for r=-5..5 and also visualize this three derivative condition? d(a)=a+b+c, d(b)=a-b+c, d(c)=a-b-c
