Hi, Ok I try to solve it. So, we have an equation: 2x4y=16
Now order y to the right side, and "anything other" to the left side: 0.5x8=y
This is a simple linear function [http://www.apaczai.elte.hu/~08amszbb/func.PNG]. Now make a product from the left side: 0.5*(x4)=y
Examine the domain (D) and the range (R) of the function. The domain is the set of real numbers, and the range is the set of real numbers evenly divisible with 0.5. So there are infinity x values, because there are infinity real numbers evenly divisible with 0.5, and because of this, there are infinity y values, and because of this there are infinity pairs of x and y values, and because of this there are infinity solutions of the equation.
I hope I helped, my english is poor especially on terminologies Bence Szasz
