2 equations:  the first one is the sum of 2 unknown numbers x and y: x + y = 72. Now the difference is 25, so x - y = 25. Solve the first equation for y: y = 72 - x. Sub that into the second equation to solve for x: x - (72 - x) = 25. x - 72 + x = 25 and 2x - 72 = 25.  Therefore, 2x = 97 and x = 48.5  That's the larger of the 2 numbers; since we subtracted y from x we defined x as the larger of the 2.  Just for fun, plug x in to find that y = 23.5
        
             
        
        
        
El concepto básico de la función es que puede tomar cualquier número de valores, pero puede devolver solo un valor. La función es como una máquina en la que podemos darle una entrada / algo y obtener una salida o un conjunto de salidas. La entrada o el conjunto de entradas se llama dominio.
