Question

2y-3x=1xy
3y+x=2xy
it's from class 10 chapter 3 pair of linear equations in two variables​

Answer 1

Answer:

divide both sides by xy

2/x-3/y=1

3/x+2/y=2

The method to solve this type of question is

Let 1/x=u and 1/y=v

2u-3v=1

3u+2v=2

Multiply 1st equation by 2 and 2nd equation by 3 and add you will get 4u+6u=2+6

10u =8

u=4/5

put this value of u in any of the above equations

you can get the value of v

u=4/5=1/x

x=5/4

Similarly you can get the value of y
