5t + (t - 3) - [(7t + 5) - (8 - 3t)]
= 5t + t - 3 - (7t + 5 - 8 + 3t)
= 6t - 3 - (10t - 3)
= 6t - 3 - 10t + 3
= -4t

5 + 2{x - 4[3x + 7(2 - x)]}
= 5 + 2[x - 4(3x + 14 - 7x)]
= 5 + 2[x - 4(14 - 4x)]
= 5 + 2(x - 56 + 16x)
= 5 + 2(17x - 56)
= 5 + 34x - 112
= 34x - 107

(6 - d)(d^2 - 5 + 3d)
= 6d^2 - 30 + 18d - d^3 + 5d - 3d^2
= - d^3 + (6d^2 - 3d^2) + (18d + 5d) - 30
= - d^3 + 3d^2 + 23d - 30
