Question

Halla x en x-2 sobre x+5 = 6/20

Answer 1

Resolver.

x - 2          6
-------- =  -----
x + 5        20

20(x - 2) = 6(x + 5)
20x - 40 = 6x + 30
20x - 6x = 30 + 40
14x = 70
x = 70/14
x = 5

Respuesta.
x = 5

Answer 2

$\frac{x-2}{x+5} = \frac{6}{20}$

20(x-2) = 6(x+5)

20x - 40 = 6x + 30

20x -6x = 30+40

14x = 70

$x = \frac{70}{14}$

x = 5
