Afla valoarea literelor . t + 35 =69 d - 25 =64 96 - s =24 42 + u =64 cu verificare Stiind ca .a =31 ,b = a + 12 , c = b -10 ,calculeaza .a + b - c . clasa 1

2
In ce clasa esti ?
clasa 1
t= 69-35 b= 31+12
t= 34 b= 43
d= 64+25 c= 43-10
d= 89 c= 33
s= 96-24 31+43-33= 74-33= 41
s= 72
u= 64-42
u= 22

T= 69-35                               b= 31+12
t= 34                                     b= 43
d= 64+25                              c= 43-10
d= 89                                    c= 33                               
s= 96-24                               31+43-33= 74-33= 41
s= 72
u= 64-42
u= 22
2014-06-10T13:24:26+03:00
T=89-35=54 ⇒ v: 54+35+89
d=64+25=89 ⇒v: 89-25=64
s=96-24=72 ⇒ v:96-72=24
u=64-42=22 ⇒ v: 42+22=64 
b=31+12=43
c=43-10=33
a+b-c=31+43-33=74-33=41
prima este inversata trebuia sa fie t +35 =69 verificarea
