Answer 1

-(1,9a-8,9b)+(0,5-b-7,1a)-(1,4b-3,9a)=-1,9a+8,9b-0,5-b-7,1a-1,4b-3,9a=-5,1a+6,5b+0,5

Answer 2

Problem Statement

The question asks to solve the following mathematical expression step-by-step and provide help: (1,9а-8,9б)+(0,5-б-7,1а)-(1,4б-3,9а)

Step 1: Break down the expression

Let's break this down term by term: (1,9а-8,9б) (0,5-б-7,1а) (1,4б-3,9а)

Step 2: Simplify each term

(1,9а-8,9б) = 1,9а - 8,9б (0,5-б-7,1а) = 0,5 - б - 7,1а (1,4б-3,9а) = 1,4б - 3,9а

Step 3: Combine like terms

Grouping like terms gives: 1,9а - 8,9б - 7,1а + 0,5 - б + 1,4б - 3,9а

Step 4: Simplify

Combining like terms: -8,9б + 1,4б = -7,5б 1,9а - 7,1а = -5,2а 0,5 - 3,9а = -3,4а

Step 5: Final expression

Therefore, the final simplified expression is: -7,5б - 5,2а - 3,4а
