To solve for x, we need to isolate it on one side of the equation.

First, let's simplify the right side of the equation:

12.5 + 2/3 = 12.5 + 0.6667 ≈ 13.1667

Now, we can rewrite the equation as:

5x = 13.1667

To solve for x, we divide both sides of the equation by 5:

(5x)/5 = 13.1667/5

x = 2.63334
