Question

Dacă x/y = 5/3 aflați valoarea raportului 3x+2y/2y-x
Va rog repedeeee!!!

Answer 1

$\dfrac{x}{y}= \dfrac{5}{3} \Rightarrow x = \dfrac{5}{3}\cdot y \\ \\ \\ \dfrac{3x+2y}{2y-3x}= \dfrac{3\cdot\dfrac{5}{3}\cdot y+2y}{2y-3\cdot\dfrac{5}{3}\cdot y}= \dfrac{5y+2y}{2y-5y}= \dfrac{7y}{-3y} = -\dfrac{7}{3}$
