Answer 3

To solve these equations, you can use basic algebraic principles:

1. For the first equation, you need to find the value of "?":

   -540 + ? = 9780

   To find the value of "?", you can isolate "?":

   ? = 9780 + 540 ? = 10320

   So, the value of "?" is 10320.

2. For the second equation, you need to find the value of "?":

   125 + ? = 250

   To find the value of "?", you can isolate "?":

   ? = 250 - 125 ? = 125

   So, the value of "?" is 125.
