Answer
$ x = \frac{9}{5}$
$y = -\frac{26 }{15}$
Work Step by Step
$x - 3y -7 $
$4x +3y -2$
Rearrange
$x - 3y = 7 $ -> equation 1
$4x +3y = 2$ -> equation 2
Add
$ x - 3y = 7 $
+ $4x +3y = 2$
$= 5x + 0 = 9$
$= x = \frac{9}{5}$
Replace x in equation 1
$ \frac{9}{5} - 3y = 7 $
$= - 3y = 7 - \frac{9}{5}$
$= -3y = \frac{35 -9 }{5} $
$ -3y = \frac{26 }{5}$
$y = -\frac{26 }{15}$
