Answer:
( -6a + 8b - 9c )
Step-by-step explanation:
Let us assume the number to be x
According to the question,
⇒ a + 3b - 8c - ( x ) = 7a - 5b + c
⇒ a + 3b - 8c - x = 7a - 5b + c
Taking all the x terms to the RHS and all the a,b,c terms to the LHS we get,
⇒ a + 3b - 8c - 7a + 5b - c = x
⇒ -6a + 8b - 9c = x
Hence the number ( -6a + 8b - 9c ) must be subtracted.
Hope it helped !!
