3c-2a-b =3 therefore b=3c-2a-3.
Substituting this into the first two equations we obtain:
10a-13c=-45.
And -4a+13c=57
Adding these equations together we obtain:
6a=12 therefore a=2. Substituting this back into 10a-13c=45 we discover that c=5
Substituting c=5 and a=2 back into one of the original equations we obtain b=8
8^2+5^2+2^2=93
93^2=8649
