+12(c2(x, y), z) -> C2(x, +2(y, z))
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [21]:

POL(+2(x1, x2)) = x1 + x2   
POL(+12(x1, x2)) = x1 + x2

POL(7) = 3   
POL(8) = 3   
POL(9) = 3   
POL(C2(x1, x2)) = 2·x1 + x2   
POL(c2(x1, x2)) = 1 + 2·x1 + x2
