La respuesta correcta es la C o numero 3

4n+20=53-2n

Se agrupan: las literales van del lado izquierdo y los numeros del lado derecho.

4n<—se queda igual.
+2n<—se pasa al otro lado con el signo contrario...estaba negativo, pasa positivo.
Esto es igual a...
53 <—está del lado derecho, se queda igual
-20<—pasa al otro lado con el signo contrario.

Entonces queda:

4n+20=53-2n

4n+2n=53-20

6n=33

n=33/6=5.5
