Question

13,14 pls am nevoie de ajutor

Answer 1

13. a+b= 6250
a = 24* b
24*b + b = 6250
25*b=6250
b=6250:25
b=250
a=24*b=>
a=24*250
a = 6000
verificare: a+b=6250
6000+250=6250
6250=6250 (A)

14. a-b=5 250
b=a:126
126:a-a=5 250
a:(126-1)=5 250
a:125=5 250
a=5 250*125
a=656 250
656 250-b=5 250
b=656 250-5 250
b=651 000
verificare: 656 250 - 651 000=5250
5 250=5 250 (A)
