Ans it fast with explanation​

Answer 1

Answer:

$a = 3 \\ \\ b = 1.$

Step-by-step explanation:

$\frac{1}{a - b} = \frac{2}{a + b} = \frac{1}{a + b - 2} \\ \\ \frac{1}{a - b} = \frac{2}{a + b} \\ \\ a + b = 2a - 2b \\ \\ 3b = a \\ \\ a = 3b \\ \\ \frac{2}{a + b} = \frac{1}{a + b - 2} \\ \\ 2a + 2b - 4 = a + b \\ \\ a + b = 4 \\ \\ solving \: these \\ \\ \\ 4b = 4 \\ \\ b = 1 \\ \\ a = 3.$
