Question

find x:y for the equation given in the picture and ask immediately

Answer 1

given :  $\frac{(4 x^{2} -3 y^{2}) }{(2 x^{2} +5 y^{2}) } = \frac{12}{19}$
now cross muliply,
$12(2 x^{2} +5 y^{2} )=19(4 x^{2} -3 y^{2} )$
then you will ge a equation hen you can solve it by subsitution, elimination or cross muliplication method.
thank you
