ContourPlot will plot the solution so a single equation. How can I plot the solution to several equations? For example,
x^2 + y^2 - z^2 == 0
x + y + z == 1
should plot a hyperbola, (NOT a cone and a plane). Essentially, I would like to plot the intersection of two surfaces.
This example is simple enough to solve analytically, but I would like a solution that works even if there is no closed form solution.
