This is a tricky one really as I’m usually quite healthy … I’ve never been seriously ill … like everyone else I sometimes get a few aches and pains or catch a cold … I can remember a few months ago I had to have time off work with a heavy cold … I had the usual symptoms … a blocked nose … sore throat … it lasted quite a while … about 2 weeks I think though I didn’t have that much time off work … for a few days I remember feeling poorly but I was over the worst of it after a few days and went back to work … I always find it’s better to be active when you feel ill as it keeps your mind off your symptoms … I think my family get a little fed up with me when I’m ill though … I tend to feel sorry for myself and lie on the sofa all day as if I’m at death’s door … but as I said earlier … on this occasion it was nothing serious and didn’t really cause me any problems …

Ta có : 2x = 5y \(\Rightarrow\frac{x}{5}=\frac{y}{2}\Rightarrow\frac{x^2}{25}=\frac{y^2}{4}\)
Áp dụng t/c của dãy tỉ số bằng nhau, ta có :
\(\frac{x^2}{25}=\frac{y^2}{4}=\frac{x^2+y^2}{25+4}=\frac{133}{29}\)
Suy ra :
+) \(\frac{x^2}{25}=\frac{133}{29}\Leftrightarrow x^2=\frac{3325}{29}\Leftrightarrow x=\sqrt{\frac{3325}{29}}\approx10,7\)
+)\(\frac{y^2}{4}=\frac{133}{29}\Leftrightarrow y^2=\frac{532}{29}\Leftrightarrow y=\sqrt{\frac{532}{29}}\approx4,3\)
Vậy \(x\approx10,7;y\approx4,3\)
