take logs of both sides..


log (5x) = log(-2)


x log (5) = log(-2)

x = log(-2)/log(5)

log (-2) is meaningless. It does not exist.

If x is a real number, 5^x is always positive. There is no real solution to this problem. And as Mark pointed out, the logarithm of a negative number does not exist.
