Question

5(y-9)+6y=4(3y-2)-21 Памагите

Answer 1

5(у-9)+6у=4(3у-2)-21
5у-45+6у=12у-8-21
5у+6у-12у=45-8-21
-у=16
у=-16
Проверка:
5(-16-9)+6·(-16)=4(3·(-16)-2)-21
           5·(-25)-96=4·(-50)-21
               -125-96=-200-21
                    -221=-221

Answer 2

I can help you solve this equation. Here are the steps:

- First, expand the brackets on both sides of the equation:

$$5(y-9)+6y=4(3y-2)-21$$ $$5y-45+6y=12y-8-21$$

- Then, simplify by collecting like terms:

$$11y-45=12y-29$$

- Next, subtract 11y from both sides:

$$-45=y-29$$

- Finally, add 29 to both sides and get the value of y:

$$y=-16$$

The solution is y = -16. I hope this helps.Ответь+подробно.+5(y-9)+6y=4(3y-2)-21+Памагите
