Answer 1

-3a +6b-4+3a+2b-3 = -3a + 3a + 6b + 2b - 4 - 3 = 8b - 7

5a -4b+2-9a-2b-5 = 5a - 9a - 4b -  2b + 2 - 5 = - 4a - 6b - 3

x+3y-7z-3x+2y-z+2z-4y+2z = x - 3x + 3y + 2y - 4y - 7z - z + 2z + 2z =
= - 2x + y - 4z

-2x+4y-5z+2y-4z+3x+3z-2x+4y = - 2x + 3x - 2x + 4y + 2y + 4y - 5z - 4z + 3z =
= - x+ 10y - 6z

-2x^2+4y-5z-3y-4z+3x+3z-2x-8 = -2x^2 + 3x - 2x + 4y - 3y - 5z - 4z + 3z - 8 =
= - 2x^2 + x + y - 6z - 8
