Answer 4

7^x=- 8^x
they never intersect on the real line

Answer 5

so the answer is no solution?

Answer 6

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

Answer 7

at no x position y is zero

Answer 8

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

Answer 9

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

Answer 10

ok, thank you very much.
