In general, an equation A(x1, ..., xn)= B(x1, ..., xn) corresponds to the situation when we have two quantities A(x1, ..., xn) and B(x1, ..., xn) which are known to be equal, we know how each of these quantities depends on the unknown parameters x1, ..., xn, and we want to find the values of the unknowns xi from this equality -- and from other similar equalities. In some practical situations, instead of two equal values, we have three (or more) quantities which are all equal to each other. In this paper, we explain how to find the unknowns xi in such situations, i.e., how to solve the corresponding "tri-quations" and "multi-quations".
