QUESTION
 

Which of the following pairs of equations represents the reduced form of the equations large dpi{80} fn_phv frac{1}{x+y}+frac{1}{x-y}=frac{6}{5};; and;; frac{2}{x+y}-frac{1}{x-y}=frac{-3}{5}?

OPTIONS
A. 

5a+b=6,2a-b=-3 , where large a=frac{1}{x+y},b frac{1}{x-y}

B. 

5a+5b=6,10a-5b=-3, where large a=frac{1}{x+y},b frac{1}{x-y}

C. 

5a+5b=-3,10a-5b=6, where large a=frac{1}{x+y},b frac{1}{x-y}

D. 

5a+b=-3,2a-b=6, where large a=frac{1}{x+y},b frac{1}{x-y}

Right Option : B

large a=frac{1}{x+y},b frac{1}{x-y}

large a+b=frac{6}{5};;and;;2a-b=frac{-3}{5}

5a + 5b = 6

10a - 5b = -3
