Question

X supra 2 = y supra 4 =z supra 3 aflatil p x y z daca x + y+z =300

Answer 1

$\frac{x}{2}= \frac{y}{4}= \frac{z}{3} = \frac{x+y+z}{2+4+3}= \frac{300}{9}= \frac{100}{3} \\ \\ \frac{x}{2}= \frac{100}{3}=>x= \frac{200}{3} \\ \frac{y}{4}= \frac{100}{3}=>y= \frac{400}{3} \\ \frac{z}{3}= \frac{100}{3}=>z=100$
