### Solve for x.

-(tan(2^(y+1) cos(x)))/(sec(2 x)+1) = sin^2(1/y)&&(-log(y)+2 i pi (left floor)(arg(y))/(2 pi)+1/2(right floor))^2/(log(2)+log(5))^2!=x

Clearly x = 7.

That's what SHE said.

Solved. Thank you for that thought-provoking, intellectually invigorating mental exercise.

X could be just about anything, since the last two terms are "!= x".

### Re: Solve for x.

For nearly any remotely sane interpretation of that pair of equations, there is a solution with x = 0. You're going to need to define the && operator for complex values before I can tell you what y is, though.

Haha, no.

This is not a forum where we do your homework for you.

Before we can solve this (which I suspect that no one can, and you just made this up to see how we would react), we have to know what the && means and where the ! is supposed to go.

Yes, if the purpose of this problem were to determine a value of x such that the equation is a true statement (if such an x exists), then clearly one should use a numerical approach. Just use a root finding algorithm.

If the purpose were to discover some novel problem solving technique in the course of the solution, then it should be stated to solve the problem analytically--because most people will refuse to go through the task if there is no interesting feature about it. The problem looks like a waste of time to me.
