S={(1,2)}
1) Let's solve this Linear System of equations, using the Elimination/Addition method
6x - 4y = -2 Multiply by -1 the whole equation
-4x - 4y = -12
-6x + 4y = 2
-4x - 4y = -12
-----------------------
-10x =-10 Divide both sides by -10
x = 1
2) We can plug into the 2nd equation, x = 1
-4x -4y = -12
-4(1) -4y= -12
-4 -4y= -12
-4y= -12+4
-4y = -8
4y = 8
y =8/4
y=2
3) Hence, the answer is S={(1,2)}
