Simplifying Expressions

To simplify the given expressions and combine like terms, we need to identify the terms that have the same variables raised to the same powers. Let's simplify each expression step by step:

1) Simplifying the expression 1 - х + 0.4у - 0.4х - 3.5 + 1.6у + 3.5:

- Combine the terms with the same variable х: -х - 0.4х = -1.4х

- Combine the terms with the same variable у: 0.4у + 1.6у = 2у

- Combine the constant terms: 1 - 3.5 + 3.5 = 1

Therefore, the simplified expression is: -1.4х + 2у + 1.

2) Simplifying the expression а²б - 2аб² + 3аб² - 4.1а²б - аб² - 0.9а²б:

- Combine the terms with the same variables а²б: а²б - 4.1а²б - 0.9а²б = -3а²б

- Combine the terms with the same variables аб²: -2аб² + 3аб² - аб² = 0аб²

Therefore, the simplified expression is: -3а²б + 0аб².
