Afla tremenul necunoscut.   a  +24=58     32+d=76    89-c=78     55-m=33   99-e=66   b-35=26

Answer 1

a= 58 - 24, deci a = 34
d= 76- 32, deci d= 44
c= 89 - 78, deci c= 11
m= 55 - 33, deci m= 22
e= 99- 66, deci e= 33
b= 35 +26, deci b= 61

Answer 2

a+24=58⇒a=58-24=34
32+d=76⇒d=76-32=44
89-c=78⇒-c=78-89=-11⇒c=11
55-m=33⇒-m=33-55⇒-m=-22⇒m=22
99-e=66⇒-e=66-99⇒-e=-33⇒e=33
b-35=26⇒b=26+35⇒b=61
