11. –5≤p≤5and–3 ≤p≤3
The least value of p can be –5 and the least value of q can be –3. Therefore, the least value of p – q = –5 – (–3) = –5 + 3 = –2
12. As per the rule of absolute function, m – 3 = 6 or m – 3 = – 6
and
8 – m= –1 or 8 – m = 1
m = 9 or m = –3
and
m = 9 or m = 7
The common solution is 9. So, the value of m= 9
