Answer 2

To solve the equation for у, you'll need to perform the necessary operations to isolate у on one side of the equation. Here are the steps:

1. First, let's simplify both sides of the equation by finding a common denominator. The common denominator for 3 and 5 is 15.

On the left side: (2.1/3) - (1.3/5)у = (4.1/3) - 3у

Multiply the first fraction by 5/5 and the second fraction by 3/3 to get a common denominator of 15: (7/15) - (2.6/15)у = (20.3/15) - 3у

2. Now, let's move all terms involving у to one side of the equation and constants to the other side. Start by adding 3у to both sides:

(7/15) - (2.6/15)у + 3у = (20.3/15)

3. Combine the terms involving у on the left side:

(7/15) + (3 - 2.6/15)у = (20.3/15)

4. Now, subtract (7/15) from both sides to isolate the у terms:

(3 - 2.6/15)у = (20.3/15) - (7/15)

5. Calculate the values on the right side:

(3 - 2.6/15)у = (20.3 - 7)/15 (3 - 2.6/15)у = (13.3/15)

6. Now, divide both sides by (3 - 2.6/15) to solve for у:

у = (13.3/15) / (3 - 2.6/15)

To simplify further, you can convert the division into multiplication by taking the reciprocal of (3 - 2.6/15), which is (15/13.3):

у = (13.3/15) * (15/13.3)

The (15/13.3) terms cancel out:

у = 1

So, у = 1 is the solution to the equation.
