Answer:
x = 4 and y = 2
Step-by-step explanation:
5/(x-1) + 1/(y-2) = 2
6/(x-1) - 3/(y-2) = 1
put 1/( x-1) = a and 1/(y-2) = b
5a + b = 2 -------(1)
6a - 3b = 1 --------(2(
om multiply by 3 in eq 1
3(5a + b = 2)
15a + 3b = 6 ------(3)
on adding eq. 3 and 2
15a + 3b = 6
6a - 3b = 1
21a = 7
a = 7/21
a = 1/3
put a in eq 1
5a + b = 2
5(1/3) + b = 2
5/3 + b = 2
b = 2 - 5/3
b = (6 - 5)/3
b = 1/3
1/(x-1) = a and 1/(y-2) = b
1/(x-1) = 1/3 and 1/(y-2) = 1/3
3 = x - 1 and 3 = y - 2
3 + 1 = x and 3 + 2 = y
x = 4 and y = 5
