Answer 1

Раскроем скобки
2,7+3у=9(у-2,1)
2,7+3у=9у-18,9
2,7+3у-9у+18,9=0
-6у=-21,6
у=3,6

Answer 2

2,7+3у=9(у-2,1)
2,7+3у=9у-18,9
3у-9у=-18,9-2,7
-6у=-21,6
у=3,6

Answer 3

Problem Statement

The given equation is: 2.7 + 3y = 9(y - 2.1).

Solution

To solve the equation, we will follow these steps:

Step 1: Distribute the 9 on the right side of the equation: - 2.7 + 3y = 9y - 18.9.

Step 2: Move all the terms with y to one side of the equation: - 3y - 9y = -18.9 - 2.7.

Step 3: Combine like terms: - -6y = -21.6.

Step 4: Divide both sides of the equation by -6 to solve for y: - y = -21.6 / -6.

Step 5: Simplify the expression: - y = 3.6.

Therefore, the solution to the equation 2.7 + 3y = 9(y - 2.1) is y = 3.6.
