Question

{2+[2222-22-(a+2)]:2+22:2-2}X2=222

Answer 1

{2+[2222-22-(a+2)]:2+22:2-2}x2=222
{2+[2200-a+2]:2+9}x2=222
[2+(2202-a)/2+9}x2=222
{4+2202-a+18}/2x2=222
(2224-a)/2x2=222
2224-a=222
-a=222-2224
-a=-2002
a=2002

Answer 2

{2+[2222-22-(a+2)]:2+22:2-2}X2=222
{2+[2222-22-(a+2)]:2+11-2}=222 :2
2+[2222-22-(a+2)]:2+11-2=111
2+[2222-22-(a+2)]:2+11=111+2
2+[2222-22-(a+2)]:2+11=113
2+[2222-22-(a+2)]:2=113-11
2+[2222-22-(a+2)]:2=102
[2222-22-(a+2)]:2=102-2
[2222-22-(a+2)]:2=100
2222-22-(a+2)=100x2
2222-22-(a+2)=200
2200-(a+2)=200
a+2=2200-200
a+2=2000
a=2000-2
a=1998
V: 1998+2=2000
