Answer 1

Răspuns:

48:12-[3x(400:e-196:4)]=1

4-[3x(400:e-49)]=1

[3x(400:e-49)]=4-1

3x(400:e-49)=3

(400:e-49)=3:3

400:e-49=1

400:e=1+49

400:e=50

e=400:50

e=8

5+3x[21+2x(584-8xi)-18x2]-160=1000

5+3x[21+2x(584-8xi)-36]=1000+160

5+3x[21+2x(584-8xi)-36]=1160

3x[21+2x(584-8xi)-36]=1160-5

3x[21+2x(584-8xi)-36]=1155

[21+2x(584-8xi)-36]=1155:3

21+2x(584-8xi)-36=385

21+2x(584-8xi)=385+36

21+2x(584-8xi)=421

2x(584-8xi)=421-21

2x(584-8xi)=400

(584-8xi)=400:2

584-8xi=200

8x i=584-200

8x i=384

i=384:8

i=48

25-[26-(5xj-9)]:5=24

[26-(5xj-9)]:5=25-24

[26-(5xj-9)]:5=1

[26-(5xj-9)]=1x5

26-(5xj-9)=5

(5xj-9)=26-5

5xj-9=21

5xj=21+9

5xj=30

j=30:5

j=6
