Math question! Probably shouldn't be as hard as I made it....?

log(x) - log(8-5x) = 2

it's log base 10, the x and 8-5x aren't subscripts

Update:

oh and showing the work would be greatly appreciated :)

    10 ^ (log(x) - log(8-5x)) = 10^2

    10 ^ log(x) * 10^-log(8-5x) = 100

    10 ^ log(x) / 10^log(8-5x) = 100

    x / 8-5x = 100

    x = 100 (8-5x)

    x = 800 - 500x

    501x = 800

    x=800/501
