Răspuns :
nr mare= a si nr mic= b
a-b= 125 ⇒a= b+125
a/b= 3(r5)⇒ a= 3b+5
b+125= 3b+5 / -5
b+120= 3b
b=60
a= 125+60= 185
a-b= 125 ⇒a= b+125
a/b= 3(r5)⇒ a= 3b+5
b+125= 3b+5 / -5
b+120= 3b
b=60
a= 125+60= 185
a - b = 125
a : b = 3 rest 5
a = 3b + 5
3b + 5 - b = 125
2b = 125 - 5
2b = 120
b = 120 : 2
b = 60
a = 3 x 60 + 5
a = 180 + 5
a = 185
a : b = 3 rest 5
a = 3b + 5
3b + 5 - b = 125
2b = 125 - 5
2b = 120
b = 120 : 2
b = 60
a = 3 x 60 + 5
a = 180 + 5
a = 185
