5t + (t - 3) - [(7t + 5) - (8 - 3t)]

= 5t + t - 3 - (7t + 5 - 8 + 3t)

= 6t - 3 - (10t - 3)

= 6t - 3 - 10t + 3

= -4t

= 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

= 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

= 6d^2 - 30 + 18d - d^3 + 5d - 3d^2

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

= - d^3 + 3d^2 + 23d - 30
