x +x +2 +x +4 = 42
3x +6 = 42
3x = 42 -6
3x = 36
x = 36/3
x = 12
Los números:
x = 12
x +2 = 12+2 = 14
x +4 = 12 +4 = 16
Respuesta: 12, 14, 16
Resolvemos
2x + 2x + 2 + 2x + 4 = 42
2x + 2x + 2x + 2 + 4 = 42
6x + 2 + 4 = 42
6x = 42 - 4 - 2
6x = 36
x = 36/6
x = 6
2x = 2 (6) = 12
2x + 2 = 2 (6) + 2 = 12 + 2 = 14
2x + 4 = 2 (6) + 4 = 12 + 4 = 16
Respuesta : Los números son : 12, 14 y 16
