Abstract
The purpose of this paper is to describe a decision algorithm for unifiability of equations w.r.t. the equational theory of two distributive axioms: x*(y+z)=x*y+x*z and (x+y)*z=x*z + y*z. The algorithm is described as a set of non-deterministic transformation rules. The equations given as input are eventually transformed into a conjunction of two further problems: One is an AC 1-unification-problem with linear constant restrictions. The other one is a second-order unification problem that can be transformed into a word-unification problem and then can be decided using Makanin's decision algorithm. Since the algorithm terminates, this is a solution for an open problem in the field of unification.
