2953. \( (2x + 2y) + (3x + 3y) = 2x + 2y + 3x + 3y = 5x + 5y \)
2955. \( (3x + y) - (2x + 2y) = 3x + y - 2x - 2y = x - y \)
2957. \( (25 + a) - (- 32 + b) = 25 + a + 32 - b = 57 + a - b \)
2959. \( (5x + 6) + (8x - 3) = 5x + 6 + 8x - 3 = 13x + 3 \)
2961. \( - (a - 101) - (1 - a) - (2 - a) = -a + 101 - 1 + a - 2 + a = a - a - a + 101 - 1 - 2 = 98 \)
2963. \( (7a + 3b + 10c) - (5a + 4b + 2c) = 7a + 3b + 10c - 5a - 4b - 2c = 2a - b + 8c \)
2965. \( (x ^ 3 + 3x ^ 2 + 2) + (x ^ 2 + 2x + 1) = x ^ 3 + 3x ^ 2 + x ^ 2 + 2x + 2 + 1 = x ^ 3 + 4x ^ 2 + 2x + 3 \)
2967. \( (3x ^ 2 - 5x) + (6x + x ^ 2 + 5) = 3x ^ 2 + x ^ 2 - 5x + 6x + 5 = 4x ^ 2 + x + 5 \)
2969. \( (x ^ 3 + 5) + (x ^ 3 + 3x ^ 2 + 17) = x ^ 3 + x ^ 3 + 3x ^ 2 + 5 + 17 = 2x ^ 3 + 3x ^ 2 + 22 \)
2971. \( (10x ^ 2 + 16) - (12x ^ 3 - 4x + 12) = 10x ^ 2 + 16 - 12x ^ 3 + 4x - 12 = -12x ^ 3 + 10x ^ 2 + 4x + 4 \)
2973. \( (6x ^ 2 - 3) - (7x + 1) - (6x ^ 2 - 2x - 3) = 6x ^ 2 - 3 - 7x - 1 - 6x ^ 2 + 2x + 3 = 2x + 2 \)
2975. \( (3x ^ 2 - 3x + 10) + (x ^ 2 - 4x + 6) = 3x ^ 2 - 3x + 10 + x ^ 2 - 4x + 6 = 4x ^ 2 - 7x + 16 \)
2977. \( (x ^ 5 + x ^ 3 + 2x + 2) + (x ^ 4 + 3x ^ 2 + 3) = x ^ 5 + x ^ 4 + x ^ 3 + 3x ^ 2 + 2x + 2 + 3 = x ^ 5 + x ^ 4 + x ^ 3 + 3x ^ 2 + 2x + 5 \)
2979. \( (2x ^ 2 - 4x + 5) - (6x ^ 2 - 9) = 2x ^ 2 - 4x + 5 - 6x ^ 2 + 9 = -4x ^ 2 - 4x + 14 \)
2981. \( (6 - 2x ^ 2 - x ^ 4) - (- 5 - 3x - x ^ 3) = 6 - 2x ^ 2 - x ^ 4 + 5 + 3x + x ^ 3 = 11 - x ^ 4 - 2x ^ 2 + x + x ^ 3 \)
2983. \( (4y ^ 2 - 5y + 6) + (y ^ 2 + 3y - 15) = 4y ^ 2 - 5y + 6 + y ^ 2 + 3y - 15 = 5y ^ 2 - 2y - 9 \)
