This requires a numerical solution method. Draw a graph first to see where the solution(s) might lie.

Humm ... I might need to slow down on the fermented bananas, I didn’t notice any mention of a graphical method by Asinus.

The graphical method may be the easiest when you are using a computerized graphing tool that iterates the value of (x) over a range that includes y=0.

Do it with graphing paper; calculate each plotted point with a calculator (or a slide rule) and then explain how it’s easier.
