    Sorry :o I'll give it a try later on... I did a very big mistake

    The only way that I see, is that you have to solve this by graphing, or iterations, if you know how to do it.

    Draw the graph of and .

    Look for the point of intersection, and check it's x coordinate, which is the solution to your answer.
