Step-by-step explanation:
Hi , Let X should be added to 7a - 9b + 13c to get 9a + b - c .
Then,
7a - 9b + 13c + x will be equal to 9a + b - c.
Now,
7a - 9b + 13c + x = 9a + b - c
x = 9a + b - c - 7a + 9b - 13c
x = 9a - 7a + b + 9b - c - 13c
x = 2a + 10b - 14c .
Hence,
2a + 10b - 14c should be added to 7a - 9b + 13c to get 9a + b - c .
