```							Dear StudentTo find the four solutions of 2x + y = 7 we substitute different values for x and y x = 0Then,2x + y = 7(2×0)+y = 7y = 7(0,7)Let x = 1Then,2x + y = 7(2×1)+y = 72+y = 7y = 7 – 2y = 5(1,5)Let y = 1Then,2x + y = 72x+ 1 = 72x = 7 – 12x = 6x = 3(3,1)Let x = 2Then,2x + y = 72(2)+y = 74+y = 7y = 7 – 4y = 3(2,3)Thus, The solutions are (0, 7), (1,5), (3,1), (2,3)Thanks
