In this thesis, we study the following system of two difference equations where r is a fixed real number. We determine the form of the general solution for this system with the following initial values in the following cases: Case: r =1 and r = 0 and r = ?1 In case r =2 we specify as follows Also we study the following system of two difference equations where r is a real number. We determine the general form of the solution for this system with the following initial values: and In case r = 0 we determine a simple general form of the solution for this system with the following initial values:
