stuck on a hard question my teacher gave me

how to solve the equation 2^x=5x using logs? note this is an exponetial equation,not a quadratic.

Show me how it possible then, or don't say it JackW ( This may be coming across as rude but I genuinely want to know this method not on the junior cert).

This is a simultaneous equation-a father and his son have a combined age of 52.8 years ago the father was 8 times the sons age .write and equation in x and y
