Answer:

hey here is your solution

pls mark it as brainliest

Step-by-step explanation:

to \: find =  \\ values \: of \: x \: and \: y \\  \\ so \: here \:given \: equations \: are  \\  \\  \frac{3a}{x}  -  \frac{2b}{y}  + 5 = 0 \\  \\ 3a \times  \frac{1}{x}  - 2b \times  \frac{1}{y }  =  - 5 \\  \\ and \\  \\  \frac{a}{x}  +  \frac{3b}{y}  - 2 = 0 \\  \\  a \times  \frac{1}{x}  + 3b \times  \frac{1}{y}  = 2

so \: let \: then \\  \\  \frac{1}{x}  = m \:  ,\:  \frac{1}{y}  = n \\  \\ resubstituting \: accordingly \\  \\ 3a m - 2bn =  - 5 \:  \:  \:  \:  \:  \:  \: (1) \\  \\ am + 3bn = 2 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: (2) \\  \\ applying \: now \\ (2) \times 3 \\  \\ 3am + 9bn = 6 \:  \:  \:  \:  \:  \:  \:  \:  \: (3) \\  \\ now \: applying \\ (3) - (1) \\  \\ 9bn - ( - 2bn) = 6 - ( - 5) \\  \\ 11bn = 11 \\  \\ bn = 1 \\  \\ n =  \frac{1}{b}  \\  \\ substitute \: value \: of \: n \: \\  in \: any \: of \: three \: equations \\  \\ we \: have \: then \\  \\ m =  \frac{ - 1}{a}

so \: accordingly \:  \\  \\  \frac{1}{x}  = m\: , \:  \frac{1}{y}  = n \\  \\  \frac{1}{x}  =  \frac{ - 1}{a}  \: , \:  \frac{1}{y}  =  \frac{1}{b}  \\  \\ x  =  - a \: \\   \\ y = b \\  \\ thus \: then \\ (x,y) = ( - a,b)
