To solve for \( x \) in the equation \( x - 2 = -10 \), we follow these steps:
- Add 2 to both sides of the equation: \[ x - 2 + 2 = -10 + 2 \] This simplifies to: \[ x = -8 \]
Now, it seems like there might be a miscommunication with the notation you used ("x 4"), but the main part of the equation is solved. Thus, the solution is: \[ \boxed{-8} \]
