Rewrite the equation using the next propierties:

Cancel logarithms by taking exp of both sides:

Multiplying both sides by -x and factoring:

Factoring:

The solutions are:

Evaluating x=-4

This is an absurd because ln(x) is undefined for 
Evaluating x=-1

Which is correct, hence the solution is:

Answer: x=2.9, y=-1.6 and x=-1.7, y=6.7
