Question

Determine os valores de x e y.​

Answer 1

Explicação passo-a-passo:

3/y = x/8 = 2/4

2/4= 3/y >>>>1

e

2/4 = x/8 >>>>2

achando y>>>>1

2/4 = 3/y

em cruz

2 * y = 4 * 3

2y = 12

y = 12/2 =6 >>>>> resposta de y

achando x

2/4 = x/8

em cruz

4 * x = 2 * 8

4x = 16

x= 16/4 = 4 >>>>> resposta x

Answer 2

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

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

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

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

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

$\dfrac{2}{4}$

2 * y = 4 * 3

2y = 12

y =   $\dfrac{12}{2}$   = 6

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

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

4 * x = 2 * 8

4x = 16  

x =   $\dfrac{16}{4}=4$
