Question

solve for x and y 2/x-1+3/y-2=1 and 5/x-1+6/y-2=7​

Answer 1

Answer:

2/x + 3/y-2 =1

5/x-1+6/y=7

Put 1/x= u

1/y= v

2u+3v=1

5u-1+6v=7

2u+3v= 1

5u+6v=7+1

2u+3v=1

5u+6v=8

2*(2u+3v)=1*2

5u+6v=8

4u+6v=2

5u+6v=8

Subtracting both eqs

-u= -6

u =6

Put value of u in eq 2u+3v=1

2*6+3v=1

12+3v=1

3v=1-12

3v=-11

v=-11/3
