[tex] \frac{x}{6} = \frac{y}{7} = \frac{z}{8} = \frac{x + y - z}{6 + 7 - 8} = \frac{20}{5} = 4[/tex]
[tex] \frac{x}{6} = 4 = > x = 6 \times 4 = 24[/tex]
[tex] \frac{y}{7} = 4 = > y = 7 \times 4 = 28[/tex]
[tex] \frac{z}{8} = 4 = > z = 4 \times 8 = 32[/tex]
[tex] \frac{24 + 28 - 32}{6 + 7 - 8} = \frac{52 - 32}{13 - 8} = \frac{20}{5} [/tex]
