$\frac{2a}{a + b - c} = \frac{2b}{b + c - a} = \frac{2c}{a + c - b} = k \\ \\ by \: theorem \: on \: equal \: ratios \\ \\ \frac{2a + 2b + 2c}{a + b - c + b + c - a + a + c - b} = k \\ \\ \frac{2(a + b + c)}{a + b + c} = k \\ \\ \therefore \: k = 2$

If f(x) = 3x - 5, than f(2) =

Mamont248 [21]

If we substitute 2 into x it'll be:

$3x - 5 \\ 3(2) - 5 \\ 6 - 5 \\ 1$
