Answer 2

Let's solve the equation step by step:

1. Start with the equation: 20 - 4y = 3(2 + y)

2. Distribute the 3 on the right side to both terms inside the parentheses: 20 - 4y = 3 * 2 + 3 * y

3. Simplify the right side: 20 - 4y = 6 + 3y

4. Now, let's isolate the variable y on one side of the equation. You can do this by adding 4y to both sides of the equation to get all the y terms on one side:

   20 - 4y + 4y = 6 + 3y + 4y

5. Simplify both sides further:

   20 = 6 + 7y

6. Next, subtract 6 from both sides to isolate the term with y:

   20 - 6 = 6 - 6 + 7y

7. Simplify both sides:

   14 = 7y

8. Finally, divide both sides by 7 to solve for y:

   14/7 = 7y/7

   2 = y

So, the solution to the equation is y = 2.
