Vì ƯCLN(x,y) = 5 \(\Rightarrow\hept{\begin{cases}x=5.m\\y=5.n\end{cases}}\)(m;n \(\in\)N và ƯCLN(m,n) = 1)

Ta có: x + y = 20

=> 5.m + 5.n = 20

=> 5.(m + n) = 20

=> m + n = 20 : 5

=> m + n = 4

Mà (m;n) = 1 \(\Rightarrow\hept{\begin{cases}m=1\\n=3\end{cases}}\)hoặc\(\hept{\begin{cases}m=2\\n=2\end{cases}}\)hoặc\(\hept{\begin{cases}m=3\\n=1\end{cases}}\)

Các cặp giá trị (a;,b) tương ứng là: (5,15) ; (10,10) ; (15,5)
