Question

olha é x-5 x+1 6 e 24

Answer 1

Teorema de Tales:

$\dfrac{x-5}{x+1}=\dfrac{6}{24}$

$\dfrac{x-5}{x+1}=\dfrac{1}{4}$

$x+1=4(x-5)$

$x+1=4x-20$

$4x-x=20+1$

$3x=21$

$x=21\div3$

$x=7$.

Answer 2

De acordo com o Teorema de Tales:

$\frac{x-5}{x+1}=\frac{6}{24}\\ \\ \frac{x-5}{x+1}=\frac{1}{4}\\ \\ 4(x-5)=x+1\\ \\ 4x-20=x+1\\ \\ 3x=21\\ \\ \boxed{x=7}$
