1. (2x8) + (4x - 5 -5y)
     16  + 4x - 5 - 5y
     16 - 5 + 4x - 5y
     11+4x-5y
     
2. (3x2 + 2 x -1) + (x2 - 5 x + 6)
    (6+2x-1)+(2x-5x+6)
    6 + 2x - 1 + 2x - 5x + 6
    6-1+6+2x+2x-5x
    11+(-1x)
     11-x
3. (2x + 5) - x - 3)
    2x + 5 -x -3
    2x-x+5-3
    x+2
4. ( X2+ 4x -1 ) - (2x2 + 4x)
   x2 + 4x - 1 - 4 - 4x
   x2 - 5
5. (y2 - 3 ) - (4y2 + 5y + 6 )
    y2-3-4y2-5y-6
    -3y2-5y-9
6 . ( 5a - 6 + ab ) - (a + 2ab - 1)
      5a-6+ab-a-2ab+1
      3ab+4a-5
