Difficult equations

Postby Guest » Tue Oct 13, 2020 12:43 pm

Hi all,

I can't figure out how I could rewrite the next equation to calculate the value of x.

log(y) = 0.207 + (-2.97-0.207)/(1+(x/14)^-0,467)) with y = 0,4857


Also on the internet it can't be solved. I thought maybe the base of the log was not equal to 10 which caused the problem, and when I calculated the base (with an known x-value) it indeed differs from 10 (the base of the log is than 9.9). Could somebody please help me.
