we can add 2 to both sides to get 3y = -y2 + 2, which simplifies to 3y = -(y2 - 2).
5y + 2(3y − 1) = 8y - (y2)
5y + 2(3y - 1) can be rewritten as 5y + 6y - 2.
Then, we can combine like terms on the left side to get
11y - 2.
On the right side, we can combine like terms to get 8y - y2.
Now, we have 11y - 2 = 8y - y2. We can subtract 8y from both sides to get 3y - 2 = -y2.
Finally, we can add 2 to both sides to get 3y = -y2 + 2, which simplifies to 3y = -(y2 - 2).
