Question

Determine os valores de x e y.

Answer 1

$\dfrac{3}{y}= \dfrac{x}{8} =\dfrac{2}{4}$

=======================

$\dfrac{2}{4}= \dfrac{3}{y} =1$

$\dfrac{2}{4}= \dfrac{x}{8} =2$

======================

$\dfrac{2}{4}$

2 * y = 4 * 3

2y = 12

y =   $\dfrac{12}{2}$   = 6

====================

$\dfrac{2}{4}=\dfrac{x}{8}$

4 * x = 2 * 8

4x = 16  

x =   $\dfrac{16}{4}=4$
