Question

Stiind ca 4x-3y/3x-y =1/5, determinați valoarea raportului nr x si y

Answer 1

$\frac{4x - 3y}{3x - y } = \frac{1}{5}$

$5(4x - 3y) = 3x - y$

$20x - 15y = 3x - y$

$20x - 3x = - y + 15y$

$17x = 14y \: | \div y$

$\frac{17x}{y} = 14$

$17 \times \frac{x}{y} = 14$

$\frac{x}{y} = \frac{14}{17}$
