Answer 2

To simplify the expression $09,(а-3б)-0,2(5б-3а)-1,7б$, let's follow the order of operations, which is parentheses, multiplication, and then addition and subtraction.

Given expression: $09,(а-3б)-0,2(5б-3а)-1,7б$

First, distribute the terms inside the parentheses:

$= 9(а-3б)-0.2(5б)-0.2(-3а)-1.7б$

$= 9a - 27б - 1б + 0.6а - 1.7б$

Now, combine like terms:

$= (9a + 0.6a) + (-27б - 1.7б - 1б)$

$= 9.6a - 29.7б$
