I want to plot a function in pgfplots using the addplot command. However, I can't solve the function for either of the variables I want to plot.

The equation is: $\frac{x}{1-.8^{10 - \frac{log(y - x)}{log(M)} - 1}} = y$

Is there a way that I can plot it even though variables appear on both sides?

I am plotting several other equations (all of which I can solve in terms of either x or y).

    No. You need to solve the equation first. Unless you do a 3d plot of "left - right" and mark the zero contour. – John Kormylo May 02 '18 at 15:03

    If there is no closed form solution you can pre-calculate a table of x,y values and plot that. – John Kormylo May 02 '18 at 15:12
