Answer:
\huge\boxed{x=3(1)/(3) \quad ;\quad y=-3}

Explanation:


\displaystyle\ \Large \boldsymbol+\ \left \{ {{6x+4y=8} \atop {-4y=12}} \right. \Longrightarrow\\\\\\ 6x+ 4y\!\!\!\!\!\diagup-4y\!\!\!\!\!\diagup=12+8 \\\\6x=20 \\\\x=(20)/(6) =(10)/(3) =3(1)/(3) \quad ; \quad y=-3

6x + 4y = 8
-4y = 12

6x + 4y = 8
y = 12/-4 = -3

6x + 4(-3) = 8
y = -3

6x -12 = 8
y = -3

x = (8+12)/6 = 10/3
y = -3 i guess
