[tex]x+y+z =20[/tex]
[tex]\frac{x}{0.2} =\frac{y}{0.6} =\frac{z}{1.2}[/tex]
[tex]\frac{x}{0.2} +y =\frac{y}{0.6}+z =\frac{z}{1.2} = \frac{x + y + z }{0.2+0.6+1.2}= \frac{20}{2}=10[/tex]
[tex]\frac{x}{0.2} = 10[/tex] [tex]x =10 \cdot 0.2 = 2[/tex]
[tex]\frac{y}{0.6} = 10[/tex] [tex]y =0.6 \cdot 10 = 6[/tex]
[tex]\frac{z}{1.2} = 10[/tex] [tex]z =1.2 \cdot 10 =12[/tex]
Sper că te-am ajutat!
Succes!
