Answer 2

To solve the inequality $5.2 - 2y > 0.5y - 20$, you can follow these steps:

1. First, let's simplify the equation by moving all terms involving $y$ to the left side of the inequality and constants to the right side:

   $5.2 - 2y - 0.5y + 20 < 0$

2. Combine like terms:

   $5.2 - 2.5y + 20 < 0$

3. Add 5.2 and 20:

   $25.2 - 2.5y < 0$

4. Now, we want to isolate $y$ by dividing both sides by -2.5. When dividing by a negative number, remember to reverse the inequality sign:

   $\frac{25.2 - 2.5y}{-2.5} > \frac{0}{-2.5}$

   $y - 10.08 > 0$

5. Now, add 10.08 to both sides:

   $y > 10.08$

So, the solution to the inequality is $y > 10.08$.
