Х+х-9-х+14=86

This is a simple algebraic equation where \( x \) represents an unknown value you need to solve for. To solve the equation, combine like terms and isolate \( x \):

\( x + x - 9 - x + 14 = 86 \)

Now combine the \( x \) terms:

\( x + x - x = x \)

So the equation simplifies to:

\( x + 5 = 86 \)

To solve for \( x \), subtract 5 from both sides:

\( x = 86 - 5 \)

\( x = 81 \)

So the solution to the equation is \( x = 81 \).
