Question

Numerele x,y,z sunt invers proportionale cu nr 1/3,1/4,1/6
Aflati nr stiind ca x/3+y/4-z/6=6

Semnul asta,,/,, inseamna supra

Answer 1

$\rm \{x,y,z\}~p.i~\{ \frac{1}{3}, \frac{1}{4}, \frac{1}{6}\} \longrightarrow \\ \\ \longrightarrow \frac{x}{3} = \frac{y}{4}= \frac{z}{6}=k \\ \\ k+\not k-\not k=6 \\ \\ \underline{k=6} \\ \\ \bold{x=3\cdot6=18} \\ \\ \bold{y=4\cdot6=24} \\ \\ \bold{z=6\cdot6=36}$
