Let the smaller number be $$x$$ and the other number be $$y$$ Acc. to ques, => $$x + 2y = 2x + 16$$ => $$2y - x = 16$$ -------------(i) Also, difference between the numbers = $$y - x = 6$$ ------------(ii) Multiplying eqn(ii) by 2 and then subtracting it from (i), we get : => $$(2y - 2y) + (-x + 2x) = 16 - 12$$ => $$x = 4$$
