its the same as the butterfly method of solving for x example 1/2 = 2/x to solve it your way is to say 1times x = 2 times 2 so 1x=4 because the 1 and the x are together it means 1 times x and to get the x alone on one side of the equation you have to divide both sides by one so 1x/x = 4/1 which is = to x=4 which means if you put 4 where the x is in your original equation both sides of your problem would be = so your answer is correct
