===================
First solve one of the equations for a variable.Let's solve equation #2 for x;
x=(2y+4)(3)/6}}}
cancel;
---------------------
Now substitute that into one of the equations;
Lets replace x in the first equation with 2y+4;
2y+8=y+12
2y-y=12-8
y=4
-----------
Now replace y in either equation with 4;
x+2=8
x=6
So your answers are;
x=6, y=4
:)
