In this paper, we study the boundedness character and persistence, existence and uniqueness of the positive equilibrium, local and global behavior, and the rate of convergence of positive solutions of the following system of rational difference equationsx n + 1 =α 1 + β 1y na 1 + b 1y n − 1,y n + 1 =α 2 + β 2x na 2 + b 2x n − 1,where the parameters α i , β i , a i , b i for i ∈{1,2} and the initial conditions x −1 , x 0 , y −1 , y 0 are positive real numbers. Some numerical example are given to verify our theoretical results. Copyright © 2015 John Wiley & Sons, Ltd.
