Answer 1

Step-by-step explanation:

i) 12a - 9ab+5b -3 -(4a -7ab+3b+12)

= 12a-9ab+5b-3 -4a+ 7ab -3b-12

=12a-4a-9ab+7ab+5b-3b -3-12

=8a- 2ab+2b-9 answer

ii) 42 -3+52 -8+7-10 from 18-3p-11q+5pq-22+52

18-3p -11q+5pq-22+52 -(42-3+52-8+7-20)

=18-3p-11q+5pq-22+52-42+3-52+8-7+20

=18-22+52-42+3-52+8-7+20-3p-11q+5pq

= -22-3p - 11q+5pq answer
