摘要
讨论了以下问题：１）方程αχβ＝γ在其有解时的性质；２）方程组αχβ＝γ，σχτ＝ρ｛有解的充要条件及通解表达式；
This paper deals with the following problems: 1) properties of the soluble equation αχβ=γ; 2) necessary and sufficient conditions for a pair of morphism equations αχβ=γ, σχτ=ρ to have a common solution, and the formula of general solution when certain conditions hold; 3) necessary and sufficient conditions for the morphism equation αφβ+σψτ=γ to have a solution, and the formula of general solution when certain conditions hold.
