Definamos las variables:

x = \text{número de bicicletas}
y = \text{número de triciclos}
z = \text{número de autitos}

Sabemos que:

1. Se producirán 10 bicicletas menos que triciclos:
x = y - 10

2. La cantidad total de juguetes es 280:
x + y + z = 280

3. El número total de ruedas es 945:
2x + 3y + 4z = 945

Sustituyendo x = y - 10 en las otras ecuaciones:

(y - 10) + y + z = 280
2(y - 10) + 3y + 4z = 945

Resolviendo primero para z :

2y - 20 + 3y + 4z = 945
5y + 4z - 20 = 945
5y + 4z = 965

De la primera ecuación:

2y + z = 290

Multiplicamos la primera ecuación por 2 para alinear los términos:

4y + 2z = 580

Restamos esta ecuación de la ecuación modificada anterior:

(5y + 4z) - (4y + 2z) = 965 - 580
y + 2z = 385
y = 385 - 2z

Sustituyendo y en la ecuación 2y + z = 290 :

2(385 - 2z) + z = 290
770 - 4z + z = 290
770 - 3z = 290
3z = 480
z = 160

Sustituyendo z de nuevo para encontrar y :

y = 385 - 2(160)
y = 385 - 320
y = 65

Y finalmente x :

x = y - 10
x = 65 - 10
x = 55

Por lo tanto, el número de juguetes de cada tipo es:

x = 55
y = 65
z = 160
