By using an argument filtering and a montonic ordering, at least one Dependency Pair of this SCC can be strictly oriented.

+12(+2(x, y), z) -> +12(y, z)
+12(+2(x, y), z) -> +12(x, +2(y, z))
Used argument filtering: +12(x1, x2)  =  x1
+2(x1, x2)  =  +2(x1, x2)
Used ordering: Quasi Precedence: trivial
