finding solutions numerically of the equation

given the equation x^5 – y^5 = 1 ,x-2y=1 i need to find the numerical values of the solutions. Now as far as i know N is the command that we’ll be using to get numerical values , NSolve for solving the equation numerically and that it must contain in the output, numbers , not symbols, but i havent been specified either to solve for x or y, nor have i been given values for any of them . if i choose to solve for x , the output gives solution containing y and solving for y gives result in x, these arent numerical forms of solutions. the N command is only used to give a value numerically. how can i get that in this equation? or maybe i can use another command that can be helpful?
