To solve the equation -2.5x + 18 - 1.6x = 5.7, you would first combine like terms to simplify the equation. Then, isolate the variable x by performing operations to both sides of the equation until x is alone on one side. Finally, divide both sides by the coefficient of x to solve for x. The steps are as follows:

- Combine like terms: -2.5x - 1.6x = -4.1x.
- Subtract 18 from both sides: -4.1x = 5.7 - 18.
- Simplify: -4.1x = -12.3.
- Divide both sides by -4.1: x = -12.3 / -4.1.
- Calculate: x = 3.

Therefore, the solution to the equation -2.5x + 18 - 1.6x = 5.7 is x = 3.
