Afla numarul necunoscut si verifica . a+325=900 550+b=703 918-c=220 d-321=599 221+114+g=900 m+255+300=899

Answer 1

a+325=900
a=900-325
a=575

575+325=900

550+b=703
b=703-550
b=153

550+153=703

918-c=220
-c=220-918
-c=-698
c=698

918-698=220

d-321=599
d=599+321
d=920

920-321=599


221+114+g=900
335+g=900
g=900-335
g=565

221+114+565=900

m+255+300=899
m+555=899
m=899-555
m=344

344+255+300=899
