Răspuns :
a - b = 20
a = b + 20
a : b = 4, rest 2
a = 4b + 2
4b + 2 - b = 20
3b + 2 = 20
3b = 18
b = 18 : 3
b = 6
a = 6 x 4 + 2
a = 26
a = b + 20
a : b = 4, rest 2
a = 4b + 2
4b + 2 - b = 20
3b + 2 = 20
3b = 18
b = 18 : 3
b = 6
a = 6 x 4 + 2
a = 26
a-b=20
a÷b=4,2⇒a=4b+2
a, b=?
4b+2-b=20
3b+2=20/÷3
b+2=6, (6)
b=4, (6)
a=4, (6)·4+2
a=18, (6)+2
a=20, (6)
