Answer 2

To solve these equations, let's go through them one by one:

1. 275 + X = 915 Subtracting 275 from both sides, we get: X = 915 - 275 X = 640

2. X + 307 = 1000 Subtracting 307 from both sides, we get: X = 1000 - 307 X = 693

3. X - 413 = 294 Adding 413 to both sides, we get: X = 294 + 413 X = 707

4. 902 - X = 732 Subtracting 902 from both sides, we get: -X = 732 - 902 -X = -170 Dividing both sides by -1 (or multiplying by -1), we get: X = 170

5. 654 + X = 903 Subtracting 654 from both sides, we get: X = 903 - 654 X = 249

6. X + 257 = 881 Subtracting 257 from both sides, we get: X = 881 - 257 X = 624

7. X - 347 = 597 Adding 347 to both sides, we get: X = 597 + 347 X = 944

8. X + 713 = 961 Subtracting 713 from both sides, we get: X = 961 - 713 X = 248

9. 315 - X = 128 Subtracting 315 from both sides, we get: -X = 128 - 315 -X = -187 Dividing both sides by -1 (or multiplying by -1), we get: X = 187

So the solutions to the equations are: X = 640, 693, 707, 170, 249, 624, 944, 248, and 187.
