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
