Hello !
Answer:
![\Large \boxed{\sf y=-27}](https://img.qammunity.org/2023/formulas/mathematics/high-school/fl9s95xwlkmezpr4v3yao4sbd08j3lglf5.png)
Explanation:
We want to find the value of y that satisfies the following equation :
![\sf (y+1)/(3) -(3y-1)/(6) =5](https://img.qammunity.org/2023/formulas/mathematics/high-school/xclbl2cco7snb93kpnil21jm6y3c6z6qgx.png)
First, multiply both sides by 6 :
![\sf 6(\sf (y+1)/(3) -(3y-1)/(6)) =6*5](https://img.qammunity.org/2023/formulas/mathematics/high-school/9vmhkyyeudd0ti1hc8fgt8069fui26bj5q.png)
Now let's expand the left side :
![\sf 2y+2-(3y-1)=30](https://img.qammunity.org/2023/formulas/mathematics/high-school/p6p5pmr0ijxd7qukrer00ckk24t53k2od5.png)
Combine like terms :
![\sf -y+3=30](https://img.qammunity.org/2023/formulas/mathematics/high-school/w1pbkwn6gomsl1rpmginmqmebfguw71k3c.png)
Now let's substract 3 from both sides :
![-\sf y+3-3=30-3\\-y=27](https://img.qammunity.org/2023/formulas/mathematics/high-school/dss84pmxsc6oyed1y4e7qlns8hfirtrbn0.png)
Finally, let's multiply both sides by -1 :
![\boxed{\sf y=-27}](https://img.qammunity.org/2023/formulas/mathematics/high-school/c0fkuo9j1gpmpm5mahwm4375dppd8o4toh.png)
Have a nice day ;)
