Question

) 7 + 9a - 7b from 2b + 4a - 6​

Answer 1

Answer:

9b - 5a - 13

Step-by-step explanation:

You haven't told us the operation needed to do so since the word 'from' is there, I am assuming and proceeding with subtraction.

(2b + 4a - 6) - (7 + 9a - 7b)  <---- (Since symbol outside bracket is -ve, the inner                      

= 2b + 4a - 6 - 7 - 9a + 7b                        signs will change accordingly)

=  2b + 7b + 4a - 9a - 6 - 7                    

=  9b - 5a - 13

Therefore, the answer is 9b - 5a - 13.
