Question

la mitad de un numero mas su consecutivo equivale a 10

Answer 1

Respuesta:

10[(3/5)x + (1/2)(x+1) = 3]

6x + 5(x+1) = 30

6x + 5x +5 = 30

11x = 30 - 5

x = 25/11

El número es  25/11

Comprobación...

(3/5)(25/11) + (1/2)((25/11)+1) = 3 

(75/55) + (1/2)((25/11)+(11/11)) = 3 

(75/55) + (1/2)(36/11) = 3 

(75/55) + (36/22) = 3 

(1650/1210) + (1980/1210) = 3

3630/1210 = 3

3 = 3
