X transpose to the right side it will be 3y= -x -2 and then 3y dividide by 3 is will be y and the -x dividide by 3 it will be -x/3 and the -2 dividide by 3 it will be -2/3
the ans.is y= -x/3 - 2/3
and the next one is same to my solving

X + 3y = -2   -----equation 1
2x - 3y = 14 ----equation 2
rearranging equation 1 you'll have:
x + 3y = -2
x = -3y - 2   -----equation 3
substituting equation 3 to equation 2 you'll have:
2x - 3y = 14
2(-3y - 2) - 3y = 14
-6y - 4 - 3y = 14
-6y - 3y = 14 + 4
-9y = 18
y = -2
substitute to equation 3
x = -3y - 2
x = -3(-2) - 2
x = 6 - 2
x = 4
