Answer 1

a) = d + k - t
б) = -m + a - c
в)  = p + n - r + s
г) = c - b - c + a - a + b = 0
д) = d - m - b + m - x - d + x = -b
е) = k - y + c + d - c - y - k + d = -2y + 2d
ё) = 9 + 2с - 8 =  2c + 1
ж) = m - 6 + 3m + 8 = 4m + 2
з) = 2m - 2n - m - n = m - 3n
и) = x - y - 2x - 2y = -x - 3y
й) = -2a - 2b + 2a - 2b = -4b
к) = 3b - 3 - 2b + 4 = b + 1
л) = -2d - 6 + 6 - 3d = -5d
м) = 5y - 2y + 2 - 3y - 12 = -10
н) = 3a - 18b + 15 + 2a + 3b - 4 = 5a - 15b + 11
o) = -8a + 12x + 20y - 80 + 3x + 60 = -8a + 15x + 20y - 20
п) = -20x + 10y - 8 + 6x - 18y + 15 = -14x - 8y + 7
р) = -6x + 4y - 3z + 12 + 6x - 8y - 10 = -4y - 3z + 2
c) = -10x - 35y + 30 + 21x + 28y - 56 = 11x - 7y - 26
т) = -6x + 15y - 18z + 15t - 33 + 2x - 2y + 14t + 40 = -4x + 13y - 18z + 29t + 7
