(6x2 + 3x - 8) + ( 2x2 - 5x - 9)


(4x2 - 9x3 + 2x4) + (8x4 - 3) + (5x3 - 7x2)


(3 - 4x3 +6x4) + (2x4 + 5) + (9x3 - 8x2)

(3x + 2x -2) + (4x - 2x + 8) = 7x + 6

(2x + 5) + ( 7x - 10) + (3x - 4) + (4x -6) = 16x - 15

(4 + 2x3) + (5x3 + 2) = 27

(6x2 + 3x - 8) + ( 2x2 - 5x - 9) = 8x2 - 2x - 17

(4x2 - 9x3 + 2x4) + (8x4 - 3) + (5x3 - 7x2) = 19

(3 - 4x3 +6x4) + (2x4 + 5) + (9x3 - 8x2) = 39

(9x + 7y4) + (5x + 3x2 - 7y4) = 3x2 + 14x

(9x2 - 5y - 12) + (8 - 9x2 + 5y + 4) = 0
