To simplify the equation:

First, distribute the negative sign in front of the second parenthesis:

(3.6x + 2.5) - 1.8x - 2.3 = 1.6x

Next, combine like terms:

3.6x - 1.8x + 2.5 - 2.3 = 1.6x

1.8x + 0.2 = 1.6x

Now, subtract 1.8x from both sides:

0.2 = 0.2x

To solve for x, divide by 0.2 on both sides:

0.2 / 0.2 = x

x = 1

Therefore, the solution to the equation is x = 1.
