Answer:

350 - 170 - 120 = r

Step-by-step explanation:

Identify the variable:

r = number of red pens

The total amount of pens ordered is 350 when adding all three colors of pens. This means we must add all of the colored pens to find the total number of pens, 350.

Write this as an equation:

170 + 120 + r = 350

Rewrite the equation to find r:

350 - 170 - 120 = r

<h2>Explicación paso a paso:</h2>

En este problema, estamos hablando del autoretrato de Leonardo Davinci. Para la resolución de este problema, necesitamos usar el cuadrado mágico de forma tal que al colocar en cada casilla los números del 1 al 16 sin repetición, entonces los números de cada fila, columna y diagonal sumen 34. De esta manera, si se colocan los números así, el resultado obtenido es 34. En la figura de abajo se encuentra el cuadrado mágico resuelto:

Columna 1:

1 + 15 + 10 + 8 = 34

Columna 2:

3 + 13 + 6 + 12 = 34

Columna 3:

14 + 4 + 11 + 5 = 34

Columna 4:

16 + 2 + 7 + 9 = 34

Fila 1:

1 + 3 + 14 + 16 = 34

Fila 2:

15 + 13 + 4 + 2 = 34

Fila 3:

10 + 6 + 11 + 7 = 34

Fila 4:

8 + 12 + 5 + 9 = 34

Diagonal 1:

8 + 6 + 4 + 16 = 34

Diagonal 2:

1 + 13 + 11 + 9 = 34

Finalmente, esta pintura fue realizada en el año 1513, que son los números de las casillas en negro.
