C) Lautaro y Facundo cuentan sus figuritas. Lautaro tiene el doble de las que tiene Facundo menos 3. Si entre los dos tienen 24 figuritas. ¿Cuántas tiene cada uno?

Lautaro has 15 figurines and Facundo has 9 figurines.

Step-by-step explanation:

Let's call the number of figurines of Lautaro 'X', and the number of figurines of Facundo 'Y'.

Lautaro has double the figurines of Facundo minus 3, so:

X = 2Y - 3

Together they have 24 figurines, so:

X + Y = 24

Using the value of X in the second equation, we have:

2Y - 3 + Y = 24

3Y = 27

Y = 9

Now, we can calculate X:

X = 2*9 -3 = 18 - 3 = 15

Lautaro has 15 figurines and Facundo has 9 figurines.
