Question

1) Nas figuras, a//b//c, calcule o valor de X​

Answer 1

Resposta:

x = 7

Explicação passo-a-passo:

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

6x + 6 = 24x - 120

24x - 6x = 6 + 120

18x = 126

x = $\frac{126}{18}$

x = 7

Answer 2

x-5/x+1= 6/24
24(x-5)=6(x+1)
24x-120=6x+6
24x-6x=6+120
18x=126
x=126/18
x=7
