Answer 2

5(6,1-4,2а)+6,3а-4,7=30,5-21а+6,3а-4,7=25,8-14,7а

Answer 3

To solve the expression, let's start by simplifying each term step by step:

1. 5(6,1 - 4,2a) = 5 * (6 - 4 * 2a) [I assume 6,1 means 6.1 and 4,2a means 4.2a] = 5 * (6 - 8a) [Now, multiply 5 by each term inside the parentheses] = 30 - 40a [Now, distribute the 5]

2. 6,3a - 4,7 = 6 * 3a - 4 * 7 [Similarly, 6,3a means 6.3a] = 18a - 28

Now, the simplified expression is:

30 - 40a + 18a - 28

Next, combine the like terms (terms with 'a' and constants):

(30 - 28) + (-40a + 18a)

2 - 22a

So, the final simplified expression is 2 - 22a.
