Answer 2

To solve the equation -3(4-5у) + 2(3-6у) = -2.6, you should first simplify the equation and then solve for the variable y. Here's how you can do it step by step:

1. Distribute the -3 and 2 on both terms inside the parentheses:

-3(4) + 3(5у) + 2(3) - 2(6у) = -2.6

2. Perform the multiplications:

-12 + 15у + 6 - 12у = -2.6

3. Combine like terms on the left side of the equation:

(15у - 12у) + (-12 + 6) = -2.6

4. Simplify further:

3у - 6 = -2.6

5. Add 6 to both sides of the equation to isolate the term with y:

3у = -2.6 + 6

6. Combine the constants on the right side:

3у = 3.4

7. Finally, divide both sides by 3 to solve for y:

y = 3.4 / 3 y = 1.1333 (rounded to four decimal places)

So, the solution to the equation is y ≈ 1.1333.
