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

Răspuns :

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=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
