A/x + b/y = m -------(1)
bx + a/y = n ---------(2)
I solve this multiplication method .becoz this way you can easily solve this type of question.
multiply a with eqn (1) and b with eqn (2)
a²/x + ab/y = ma
b²/x + ab/y = nb
=================
subtracting
a²/x - b²/x = ma - nb
( a² - b²)/x = ( ma - nb)
x = (a² - b²)/( ma - nb)
similarly multiply b with equation (1) and a with equation (2) and subtracting
you get ,
b²/y - a²/y =( mb - na)
y = ( b² - a²)/( mb - na)
hope this will help you
