    7^x=- 8^x they never intersect on the real line http://www.wolframalpha.com/input/?i=7^x%3D-+8^x

    just to clarify the problem says y equals that expression and wants it solved for x in terms of y.

    Ok, so it is no solution or what? I just want to make sure I'm understanding you right.

    There is no real solution, there may be imaginary ones.
