Answer:

x = 4 ; y = 1

Step-by-step explanation:

 \frac{6}{x - 1}  -  \frac{3}{y - 2}  = 1 \:  \:  \frac{5}{x - 1}  +  \frac{1}{y - 2}  = 2 \\ let \:  \frac{1}{x - 1}  = a \:  \:  \:  \:  \frac{1}{y - 2}  = b \\ 6a + 3b = 1  \:  \: equ \: (1) \\ 5a - 1b = 2 \:  \:  \:  \: equ \: (2) \\ multiply \: equ \: (2) \: with \: 3 \\ 15a - 3b = 6 \:  \:  \: equ \: (3) \\ add \: equ \: (1) \: and \: (3) \\ 21a = 7 \\ a =  \frac{7}{21}  \\ a =  \frac{1}{3}  \\ substitute \: a =  \frac{1}{3} in \: equ \: (1) \\ 6( \frac{1}{3})  + 3b = 1 \\ 2 + 3b = 1 \\ 3b = 1 - 2 \\ 3b =  - 1 \\ b =  -  \frac{1}{3}  \\ a =  \frac{1}{x - 1}  =  \frac{1}{3}  \\ x - 1 = 3 \\ x = 3 + 1 \\ x = 4 \\  \\ b =  \frac{1}{y - 2}  =  -  \frac{1}{3}  \\ y - 2 =  - 3 \\ y =  - 3 + 2 \\ y =  - 1

x = 4 ; y = 1

Hope you get your answer
