If a manual invoice is required:

I would create a sketch of the functional graphs to be able to determine approximation values (x_n) for the intersections and then use an approximation method, e.g. the newton method.

x_n+1 = x_n – f(x_n) / f'(x_n)

He would solve the task with the help of a function plotter and give me an overview:

Now you can look at the two intersections in greater resolution:

S1(0,797) / 1,974)

S2(-0.989 / -1,033)
