Solve the Linear Equation: -3 + X = -8 for X

To solve the equation $-3 + x = -8$, we need to isolate the variable $x$. We can do this by eliminating the constant term on the side with the variable.

Step 1: Add 3 to both sides of the equation to cancel out the $-3$ next to $x$.
This gives us:

$-3 + x + 3 = -8 + 3$

Step 2: Simplifying both sides of the equation results in:

$x = -5$

Therefore, the solution to the equation is $x = -5$, which matches choice 2.
