how to solve an equation?
Asked by | 07 Mar, 2009, 09:36: PM
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 .
