Question

What should be subtracted from 3a + 8b + 10 to get – 3a + 7b + 16?

Answer 1

Answer:

6a+b-6

Step-by-step explanation:

Let the number to be subtracted be 'k'.

Then, acc to the condition,

3a+8b+10-k= -3a+7b+16

3a+8b+10+3a-7b-16=k

6a+b-6=k

or

k=6a+b-6.

This is the answer according to me.

Sorry, if any error is there.
