Răspuns :

1100-[(128X4-144:x)X2]-171=1
1100-[(512-144:x)X2]-171=1
1100-[(512-144:x)X2]=1+171
1100-[(512-144:x)X2=172
1100-(512-144:x)=172:2
1100-(512-144:x)=86
512-144:x=1100-86
512-144:x=1014
144:x=1014-512
144:x=502
x=
[(512-144÷x)×2]-171=1
[(368÷x)×2]=171+1
(368÷x)×2=172
368÷x=172÷2
368÷x=86
x=368×86
×=31678
