Question

√5x-√7y=0 , √3y+√13x=0

Answer 1

$\sqrt{5} x - \sqrt{7} y = 0 \\ \sqrt{13}x + \sqrt{3} y = 0 \\ multiply \: \: first \: equation \: by \: \sqrt{3} \\ \: \: \: and \: second \: by \: \sqrt{7} \\ \sqrt{15}x - \sqrt{21}y = 0 \\ \sqrt{91} x - \sqrt{21}y = 0 \\ subtract \: both \: equations \\ \sqrt{15} x - \sqrt{91}x = 0 \\ x( \sqrt{15} - \sqrt{91} ) = 0 \\ x = 0 \\ y = 0$
