Euler function φ(n)is a very important function in number theory,where n is a positive integer.The solvability of binary variable coefficient Diophantine equation φ(xy)=5φ(x)+11φ(y)involving Euler functionφ(n)was discussed,and the all positive integer solutions were given by using elementary method.
