Responder:

x = 40

y = 120

z = 80

Explicación paso a paso:

Número dividido = 240

Las 3 partes:

x, y, z

y = 3x

Z = 3x - 40

x + y + z = 240

x + 3x + 3x - 40 = 240

7x - 40 = 240

7x = 240 + 40

7x = 280

x = 280/7

x = 40

y = 3 (40)

y = 120

z = 3x - 40

z = 3 (40) - 40

z = 120 - 40

z = 80
