{160-[(y:27+18):5x200-1]:9}:7=2011-2004 =>{160-[(y:27+18):5x200-1]:9}:7=7
{160-[(y:27+18):5x200-1]:9}=49
[(y:27+18):5x200-1]:9=111
[(y:27+18):5x200-1]=999
{[200*(y:27+18)]/5-1}=999 1/5*200=200/5=40
[200*(y:27+18)]/5=1000
200:5*(y:27+18)=1000
(y:27+18)=1000:40
(y:27+18)=25
y:27=25-18
y:27=7
y=7*27
y=189
a/b*x=ax/b
adica ca in cazul nostru (y:27+18):5*200
a=(y/27+18)
b=5
x=200
inlocuim in formula a/b*x=ax/b si avem:
[(y/27+18)*200]/5
