Question

5 by x-1 +1by y-2=2 and 6 by x-1 - 3by y-2=1​

Answer 1

Answer:

y =5

Step-by-step explanation:

5/x-1+1/y-2=2 ---) 1

6/x-1-3/y-2=1 ---) 2

let assume,  1/x-1=u, 1/y-2=v

multiply equation 1 by 3, we will get  

15* u = 3* v = 6  ---) 3

add equation  2 and 3

21* u = 7

u = (1/3)

x - 1=3

x = 4

b=1/3

y – 2 = 3

y = 5
