Question

la suma de tres numeros impares consecutivos es 69. busca los numeros (21,23,25)

Answer 1

Los números :2x + 1, 2x + 3, 2x + 5

Resolvemos : 

2x + 1 + 2x + 3 + 2x + 5 = 69

2x + 2x + 2x + 1 + 3 + 5 = 69

6x + 6 = 69

6x = 69 - 9

6x = 60

x = 60/6

x = 10

2x + 1 = 2 (10) + 1 = 20 + 1 = 21
2x + 3 = 2 (10) + 3 = 20 + 3 = 23
2x + 5 = 2 (10) + 5 = 20 + 5 = 25

Solución : Los números son : 21, 23 y 25
