I’m not sure where the missing sign(s) are in the string "4x84x + ?". Could you confirm the exact equation?

A likely intended version is
4x − 8 = 4x + ?
(which matches the characters “4x84x + ?” if the “−” and “=” were dropped).
For that equation subtract 4x from both sides: −8 = ?, so ? = −8. Then the two sides are identical and the equation is true for every x (infinitely many solutions).

If you meant a different placement of the signs (for example 4x = 4x + ? or 4x = 84x + ?), tell me and I’ll give the corresponding answer.
