Answer:
x = 4 and y = 5
Step-by-step explanation:
Given: [5/(x–1)] + [1/(y– 2)] = 2 , [6/(x–1)] – [3/(y–2)] = 1
Let 1/(x-1) = u and 1/(y-2) = v
Then we get equations as:
5u + v = 2 -------(1)
6u - 3v = 1 ------(2)
(1) * 3 ==> 15u + 3v = 6
(2) ==> 6u - 3v = 1
Adding==> 21u = 7
u = 7/21 = 1/3
Substuting u in equation 2, we get:
6 (1/3) - 3v = 1
-3v = 1-2
v = -1/-3 = 1/3
1/x-1 = 1/3, so x-1 = 3, x = 4.
1/y-2 = 1/3, so y-2 = 3, y = 5.
Plz mark as brainliest..
thanks..
hope it will help u.
