Answer 2

5a +b -6 should be subtracted from 2a+8b+10 to get -3a+7b+16

Explanation:

• Let X be subtracted from 2a +8b +10, it can be written as

        2a +8b +10 -X = -3a +7b+16

   ⇒ -X = -3a +7b +16 -2a -8b -10

   ⇒ -X = -3a -2a +7b -8b +16 -10

   ⇒ -X = -5a -b +6

       After divide by (-) to both side

       X = 5a +b -6
