Answer 2

Question : subtract 4a-7b+3b+12 from 12a-9b+5b-3

(notice that 7b and 3b are like terms and 9b and 5b too, so we add them)

4a-4b+12 from 12a-4b-3

12a-4b-3 - (4a-4b-12)

(when we remove the brackets, the signs change, like minus minus becomes plus and so on)

12a-4b-3-4a+4b+12

(grouping like terms)

12a-4a-4b+4b-3+12 ( 4b gets cancelled as, 1-1 = 0, just like that here, 4b-4b = 0)

12a-4a-3+12

=8a+9
