Ola Matheus

8^(x - 1) = (1/16)^(3x - 2)

8^(x - 1) = 16^(2 - 3x)

2^(3x - 3) = 2^(8 - 12x)

3x - 3 = 8 - 12x

3x + 12x = 8 + 3

15x = 11

x = 11/15 

--------------------------------------------------------------------------------

8^(x + 1) = (1/16)^(3x - 2)

8^(x + 1) = 16^(2 - 3x)

2^(3x + 3) = 2^(8 - 12x)

3x + 3 = 8 - 12x

3x + 12x = 8 - 3

15x = 5

x = 5/15 = 1/3
