1,Jika di ketahui f (x)= x-3/x+2, HITUNGLAH f (3y) 2, selesaikanlah sistem brikut secara aljabar 1/x + 2/y=2 2/x - 2/y=1

[tex]1. \\ f(x) = \frac{x - 3}{x + 2} \\ f(3y) = \frac{3y - 3}{3y + 2} \\ \\ 2. \\eliminasi \\ ( \frac{1}{x} + \frac{2}{y} = 2) + ( \frac{2}{x} - \frac{2}{y} = 1) \\ \frac{3}{x} = 3 \\ x = 1 \\ subs \: x \\ \frac{1}{x} + \frac{2}{y} = 2 \\ \frac{1}{1} + \frac{2}{y } = 2 \\ \frac{2}{y} = 1 \\ y = 2[/tex]
