Question

2×{5+3×[2+3×(2+3m)]}-2=2000

Answer 1

2×{5+3×[2+3×(2+3m)]}-2=2000

2×{5+3×[2+3×(2+3m)]}=2000+2=2002

{5+3×[2+3×(2+3m)]}=2002:2=1001

3×[2+3×(2+3m)]=1001-5=996

[2+3×(2+3m)]=996:3=332

3×(2+3m)=332-2=330

(2+3m)=330:3=110

3m=110-2=108

m=108:3

m=36

Answer 2

2×{5+3×[2+3×(2+3m)]}-2=2000
2×{5+3×[2+3×(2+3m)]}=2000+2
2×{5+3×[2+3×(2+3m)]}=2002
5+3×[2+3×(2+3m)]=2002:2
5+3×[2+3×(2+3m)]=1001
3×[2+3×(2+3m)]=1001-5
3×[2+3×(2+3m)]=996
2+3×(2+3m)=996:3
2+3×(2+3m)=332
3×(2+3m)=332-2
3×(2+3m)=330
2+3m=330:3
2+3m=110
3m=110-2
3m=108
m=108:3
m=36
