Question

18-3у-(21-5у)=43-(17+3у)

Answer 1

Ответ:

5,8

Пошаговое объяснение:

18-3y-21+5y=43-17-3y

-3y+5y+3y=43-17-18+21

5y=29

y=29/5=5,8

Answer 2

To solve for the value of y in the equation:

18 - 3y - (21 - 5y) = 43 - (17 + 3y)

You can start by simplifying the equation step by step:

1. First, distribute the negative sign on both sides of the equation:

18 - 3y - 21 + 5y = 43 - 17 - 3y

2. Now, combine like terms on both sides of the equation:

(-3y + 5y) + (18 - 21) = (43 - 17) - 3y

3. Combine the y terms on the left side and the constant terms on the right side:

2y - 3 = 26 - 3y

4. Add 3y to both sides of the equation to isolate the y terms on the left side:

2y + 3y - 3 = 26

5. Combine the y terms on the left side:

5y - 3 = 26

6. Add 3 to both sides of the equation:

5y = 26 + 3

7. Simplify the right side:

5y = 29

8. Finally, divide both sides by 5 to solve for y:

y = 29 / 5

So, the solution for y is:

y = 29/5
