Answer 1

Resposta:

$\sf \dfrac{8}{x + 8} = \dfrac{10}{2+10}$

$\sf \dfrac{8}{x + 8} = \dfrac{10}{12}$

$\sf \dfrac{8}{x + 8} = \dfrac{5}{6}$

$\sf 5 \cdot (x+ 8) = 8 \cdot 6$

$\sf 5x + 40 = 48$

$\sf 5x = 48 - 40$

$\sf 5x = 8$

$\sf x = \dfrac{8}{5}$

$\boxed{ \boxed { \boldsymbol{ \sf \displaystyle x = 1, 6 }}} \quad \gets \mathbf{ Resposta }$
