Total animales = x
Total gallinas = x/2
Total patos = x/3
Total pavos = x/10
Total pollos = 150
x = x/2 + x/3 + x/10 + 150
x - x/2 - x/3 - x/10 = 150
30x/30 - 15x/30 - 10x/30 - 3x/30 = 4500/30 Simplificas el 30
(30x - 15x - 10x - 3x) = 4500
30x - 28x = 4500
2x = 4500
x = 4500/2
x = 2250
Respuesta.
Hay 2250 animales
mcm = 30
15x + 10x + 3x + 4500 = 30x
28x + 4500 = 30x
4500 = 30x - 28x
4500 = 2x
4500/2 = x
2250 = x
Hay 2250 animales en el corral
