iii) 3a + 5 -8a + 1 
  = 3a -8a + 5 + 1 
  = -5a + 6 
here a = - 1 
so , 
answer is => -5 (-1) + 6 
                  => 5+6 
                  => 11

iv) 10 - 3b - 4 - 5b 
 = 10 - 4 -3b - 5b 
 = 6 - 8b 
 = 2(3 - 4b) 

here b = -2 
So 
Answer is => 2[3 - 4(-2)]
                  => 2[3+8]
                  => 2 x 11 = 22
