Given the difference:
![\begin{gathered} \; \; 9\text{ a 1} \\ -7\text{ 2 b} \\ ---- \\ \; \; c\text{ 8 2} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5C%3B%20%5C%3B%209%5Ctext%7B%20%20%20a%20%20%20%201%7D%20%5C%5C%20-7%5Ctext%7B%20%20%202%20%20%20b%7D%20%5C%5C%20----%20%5C%5C%20%5C%3B%20%5C%3B%20c%5Ctext%7B%20%20%20%208%20%20%20%202%7D%20%5Cend%7Bgathered%7D)

![\begin{gathered} 10-2=8 \\ 10+1=11 \\ \text{Therefore, a=1} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%2010-2%3D8%20%5C%5C%2010%2B1%3D11%20%5C%5C%20%5Ctext%7BTherefore%2C%20a%3D1%7D%20%5Cend%7Bgathered%7D)
Lastly:

We then have:
