To solve this equation, we need to combine like terms on both sides of the equation.

On the left side:
-1/3 - 9/12 = -4/12 - 9/12 = -13/12

On the right side:
-2/6 + 1/4 = -4/12 + 3/12 = -1/12

So the equation becomes:
х - 13/12 = х - 1/12

Now, subtract х from both sides to get:
-13/12 = -1/12

This is not a true statement, so there is no solution to this equation.
