how to solve an equation?
So, the equations become,
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 .
