2)мы должны прибавить одинаковые числа х к х а числы к числам

Answer 2

To simplify the expression 5,2x - (2/9 - x) + (5/18 - 2,7x), let's break it down step by step:

1. Distribute the negative sign in front of the parentheses: 5,2x - 2/9 + x + 5/18 - 2,7x

2. Combine like terms: (5,2x + x - 2,7x) - 2/9 + 5/18

3. Simplify the x terms: (5,2 - 2,7 + 1)x - 2/9 + 5/18

4. Combine like terms: (3,5)x - 2/9 + 5/18

5. Find a common denominator for the fractions: The common denominator for 9 and 18 is 18, so we multiply the first fraction by 2/2 and the second fraction by 1/1: (3,5)x - (4/18) + (5/18)

6. Combine the fractions: (3,5)x + (1/18)

Therefore, the simplified expression is (3,5)x + 1/18.
