Question

What should be Subtracted from 5a+5b+5to get 2a+2b

Answer 1

Answer:

3a + 3b + 5

Step-by-step explanation:

Let the number that need to be subtracted be N.

So, 5a + 5b + 5 - N = 2a + 2b

⇒ N =  5a + 5b + 5 - (2a + 2b)

⇒  N =  5a + 5b + 5 - 2a - 2b

⇒ N =  3a + 3b + 5

So, the number that needs to be subtracted be 3a + 3b + 5
