Answer 1

Answer:

$\frac{a + b}{z} = \frac{b + c}{x} = \frac{c + a}{y}$

Step-by-step explanation:

$\frac{a}{y + z - x} = \frac{b}{z + x - y} = \frac{c}{x + y - z} \\ \\ \\ \\ \frac{a + b}{z + x - y +z + x - y } = \frac{b + c}{z + x - y + x + y - z} = \frac{c + a}{x + y - z + y + z - x} \\ \\ \\ \\ \\ \frac{a + b}{2z} = \frac{b + c}{2x} = \frac{c + a}{2y} \\ \\ \\ \frac{a + b}{z} = \frac{b + c}{x} = \frac{c + a}{y}$
