Answer:

100*x + 14*y

Step-by-step explanation:

Tenemos que en el sistema decimal un número de 3 cifras se representa de este modo:

100*x + 10*y + z

También es llamado descomposición polinómica y de esta manera podremos encontrar la expresión algebraica.

Nos dicen la relación entre unidades y decenas, 4 veces mayor las unidades que las decenas, por lo tanto:

z = 4*y

Reemplazamos y nos queda:

100*x + 10*y + 4*y

reduciendo nos queda:

100*x + 14*y

Por lo tanto esta sería la expresión algebraica.
