Question

24 si 26 va rog!!!!!!!

Answer 1

$\frac{x}{7} = \frac{y}{3} = \frac{z}{1} =k$
x = 7k
y = 3k
z = 1k
8x - 5y = 2
8*7k - 5*3k = 2
56k - 15k = 2
41k = 2
k = $\frac{2}{41}$

x = $7 * \frac{2}{41} = \frac{14}{41}$ 
y = $3 * \frac{2}{41} = \frac{6}{41}$
z = $\frac{2}{41}$

xyz = $\frac{14}{41} * \frac{6}{41} * \frac{2}{41} = \frac{168}{68921}$
