Answer: No solution
Explanation:
Put both of the equations into y=mx+b form
6x + 2y = 12
-6x -6x
2y = -6x + 12
/2 /2 /2
y=-3x+6
-3x - y = -6
+3x +3x
-y = 3x - 6
/-1 /-1 /-1
y = -3x + 6
Your slopes are the same so that means the lines are parallel. They won't touch so that means that you have no solution.
