how to solve an equation?

Asked by  | 7th Mar, 2009, 09:36: PM

Expert Answer:

put

1/(x-y)=u

and

1/(x+y)=v

So, the equations become,

3u-5v=-2

2u-3v=13/6

Solve for u and v.

The substitute u as 1/(x-y)

and v as 1/(x+y)

this will geive you two equations in  x and y.

Solve them to get the values of x and y.

Always pl. check up the question  prpoperly, copy it down correctly and then start doing. In linear equations, one small mistake of  copying a + or a -  sign can cause you dearly as the calculations may get difficult in that case .
