For example, if you were given the line y = 3x and the logarithm y = log(x) + 5, to find the point(s) of intersection between them, you'd have to solve the equation 3x = log(x) + 5. I have no idea how to solve that for x.

Online graphing calculators show that there are actually two intersections in this example: (0.0001, 0.9897), (1.7475, 5.2424).

Is there an easy solution I'm missing, or do I need to learn something new (heaven forbid )?
