Question

Si: a/b = 1/4 ; además: a + 3/ b + 3 = 1/3
Calcular a + b

Answer 1

Hola! ლ(ಠ益ಠლ)

De aqui a/b = 1/4 sacamos que a = k y b = 4k

$\frac{a + 3}{b + 3} = \frac{1}{3} \\ \\ \frac{k + 3}{4k + 3} = \frac{1}{3} \\ \\ 3(k + 3) = 4k + 3 \\ \\ 3k + 9 = 4k + 3 \\ \\ k = 6$

Reemplazamos k en a y b

a = k = 6
b= 4k = 24

=> a + b = 30
