Answer 3

Let's solve the equation step by step:

5(2y - 1) - (5 - 2y) + 1 = 3

First, let's simplify the expression inside the parentheses:

10y - 5 - (5 - 2y) + 1 = 3

Now, let's simplify the expression inside the parentheses again:

10y - 5 - 5 + 2y + 1 = 3

Combine like terms:

12y - 9 = 3

Next, let's isolate the term with the variable on one side of the equation. To do that, we can add 9 to both sides:

12y - 9 + 9 = 3 + 9

This simplifies to:

12y = 12

Finally, let's solve for y by dividing both sides of the equation by 12:

12y/12 = 12/12

The result is:

y = 1

Therefore, the solution to the equation is y = 1.
