Solve the Linear Equation: Find X in -8 - x = -5

To solve the equation $-8 - x = -5$, we'll isolate the variable $x$ by performing algebraic operations:

Step 1: Add 8 to both sides of the equation to eliminate the $-8$:

$-8 - x + 8 = -5 + 8$

This simplifies to:

$-x = 3$

Step 2: To solve for $x$, we need to change the sign of $x$. Multiply both sides by $-1$:

$x = -3$

Therefore, the solution to the equation is $\boxed{-3}$.
