Responder:
10 (2ny- (x-y))
Explicación paso a paso:
Dada la expresión 10ny-10x + 10ny + 10y, para simplificar la expresión, se deben seguir los siguientes pasos;
Paso 1; Separa la expresión en términos similares
= 10ny-10x + 10ny + 10y
= (10ny + 10ny) - (10x + 10y)
Paso 2: Factoriza los valores comunes en ambos paréntesis
10ny (1 + 1) - 10 (x-y)
= 10ny (2) - 10 (x-y)
= 20ny - 10 (x-y)
Factoriza nuestro valor común en ambos términos:
= 10 (2ny- (x-y))
