Answer:
d) 8x -[16y-{3x+12y+x+8y}+x]
8x-[16y-4x-20y+x]
8x-[-4y-3x]
8x+4y +3x
11x+4y
e) a-[2b+{3c-3a+a+2b-3c}]
a-[2b+{-2a-2b}]
a-[2b-2a-2b]
a+2a
3a
f) 3b-[5a-{6a+2(10a-b)}]
3b-[5a-{6a+20a - 2b}]
3b-[5a-26a+2b]
3b-[21a+2b]
3b-21a-2b
b - 21a
g) -20(a-d) +3(b-c) -2[b+c+d - 3{c+d - 4(d-a)}]
-20(a-d) +3(b-c) -2[b+c+d - 3{c+d-4d+4a}]
-20(a-d) +3(b-c) -2[b+c+d-3{c-3d+4a}]
-20(a-d) +3(b-c) -3[b+c+d-3c+9d-4a]
-20(a-d) +3(b-c) -3b+6c-30d+12a
-20a+20d+3b-3c-3b+6c-30d+12a
-8a-10d+3c
h) 2(3b-5a)-7[a-6{2-5a+5b}]
2(3b-5a)-7[a-12+30a-30b]
2(3b-5a)-217a+84+210b
6b-10a-217a+84+210b
216b-227a+84
i) 5[a-2{a-2(a-2a+3a)}]
5[a-2{a+8a}]
5[a- 18a]
5a-90a
-85a
