Question

solve this class 10
solve for x and y​

Answer 1

Step-by-step explanation:

let 1/x+2y=u. and 1/x-2y. =v

then. 6u+5v=-3...................1

3u+7v. =-6..................2

42u+35v= -21..............3

15u+35v=-30...............4

- - =+

27u= 9

u= 9/27

u=1/3

keep the value of u in equeletral. 2

3u+7v= -6

3*1/3+7v=-6

1+7v=-6.

7v= -6-1

7v=-7

v= -1

keep the value of u and v above eque.

1/x+2y=1/3

x+2y =3. ............5

x-2y. =-1................6

2x= 2

x=1

1+2y=3

2y. =3-1

2y =2

y= 1
