It looks like you're trying to solve the equation $-3 + 2x = 8.6$. Let's solve it step by step.

Step 1: Add 3 to both sides of the equation to isolate the term with $x$.

$-3 + 3 + 2x = 8.6 + 3$ $2x = 11.6$

Step 2: Divide both sides by 2 to solve for $x$.

$x = \frac{11.6}{2}$ $x = 5.8$

So, the solution is $x = 5.8$.
