Question

Encontre o valor de X ​

Answer 1

6 / x + 2  = 10 / 3x - 5

6(3x - 5) = 10(x + 2)

18x - 30 = 10x + 20

18x - 10x = 20 + 30

8x = 50

x = 50/8

x = 25/4

Answer 2

10/3x-5 = 6/x+2

agora é só multiplicar cruzado :

10.(x+2) = 6.(3x-5)

10x + 20 = 18x - 30

18x - 10x = 30 + 20

8x = 50

x = 50/8 = 25/4
