HEY MATE HERE'S THE ANSWER....... ❤️❤️❤️❤️❤️

GIVEN :

$4x - 3y = 5 \: \: \: and \: \: \: 6x - 9y = 3$

TO FIND : VALUE OF X AND Y

SOLUTION :

$4 x - 3y = 5 \\ = > multiply \: both \: sides \: by \: - 3 \\ = > - 12x + 9y = - 15.........eq {}^{1} \\ \\ 6x - 9y = 3 \\ = > multiply \: both \: sides \: by \: 2 \\ = > 12x - 18y = 6..........eq {}^{2} \\ \\ \\ now \: add \: eq {}^{1} and \: eq {}^{2} \\ you \: will \: get \\ - 9y = - 9 \\ = > y = 1 \\ \\ put \: y = 1 \: in \: eq2 \: \: \\ you \: will \: get \: \\ \\ 12x = 24 \\ therefore \\ x = 2$
