Explicație pas cu pas:
[tex]\frac{x}{ \frac{1}{3} } = \frac{y}{ \frac{1}{4} } = \frac{2}{ \frac{1}{z} } \iff 3x = 4y = 2z \\ [/tex]
[tex]3x = 4y \iff 6x = 8y[/tex]
[tex]9x - 8y + 2z = 10 \iff 9x - 6x + 3x = 10 \\ 6x = 10 \implies x = \frac{5}{3} [/tex]
[tex]4y = 3 \cdot \frac{5}{3} \implies y = \frac{5}{4} \\ 2z = 3 \cdot \frac{5}{3} \implies z = \frac{5}{2}[/tex]
