To solve this equation, we need to find the value of x.

Starting with the equation:

2x + 1/1.3 = 2.5/0.65 * 2.7/9 = 1/1 / 5 / 3x + 1

We can simplify this equation by converting all the numbers to decimals:

2x + 0.769 = 3.846 * 0.3 = 1/1 / 5 / 3x + 1

2x + 0.769 = 1.15 = 3x + 1

Now, we can solve for x by moving all terms involving x to one side of the equation:

2x - 3x = 1 - 0.769

-x = 0.231

x = -0.231

Therefore, the value of x is -0.23.
