Break out the y

[DDIV]

Hi everybody

I solved the problem by making a small converging iterative loop in a software, but I cant stop thinking about this equation where I want to get a y=f(x) function.

This is how it looks:
a and b are constants and x is a variable and ln is the natural logarithm

-a*(y^0.78)+ln(y^0.22) = b*x

The classic log rules dont hep me , can somebody solve this?

When the variable of interest is found both inside and outside a log, it typically can't be isolated algebraically.

You have to use some sort of numerical approximation algorithm, which is evidently what you have done.
