The unknown value is 5.

To have an equation which has no solutions, you need to end up with a false statement, and no variable.

If there are no variables left, it means they need to be equal on each side, so they cancel each other out.

$?x-11 = 5x-6$

$5x-11 = 5x-6" "$ leads to:

$-11 = -6" "$ which can also be written as:

$0 = 5" "larr$ which is obviously false!

The unknown value is 5.
