To solve the equation $2x - 5 = 8$, we need to isolate the variable $x$. Here's the step-by-step solution:

1. Start with the equation: $2x - 5 = 8$

2. Add 5 to both sides to eliminate the $-5$ on the left: $2x - 5 + 5 = 8 + 5$ Simplifying this, we get: $2x = 13$

3. Divide both sides by 2 to solve for $x$: $x = \frac{13}{2}$ Simplifying, we find: $x = 6.5$

So, the solution is $x = 6.5$.
