Answer 2

It looks like you have three different equations involving variables (a, x, and y). Let's solve each of them:

1. 9a - 3a - a: Combine like terms on the left side: 9a - 3a - a = (9 - 3 - 1)a = 5a

   So, the solution for this equation is: 5a

2. 5x + 7x: Combine like terms on the left side: 5x + 7x = (5 + 7)x = 12x

   So, the solution for this equation is: 12x

3. 6y + 3y + y: Combine like terms on the left side: 6y + 3y + y = (6 + 3 + 1)y = 10y

   So, the solution for this equation is: 10y

To summarize:

1. The solution for the first equation is 5a.
2. The solution for the second equation is 12x.
3. The solution for the third equation is 10y.
