Final answer:
To solve the system of equations using the substitution method, solve one equation for one variable and substitute that expression into the other equation. The correct ordered pair is (0, 6).
Step-by-step explanation:
To solve the system of equations using the substitution method, we need to solve one equation for one variable and substitute that expression into the other equation. Let's solve the first equation for y:
2y = 12 => y = 6
Now, substitute y = 6 into the second equation:
-x + y = 6 => -x + 6 = 6 => -x = 0 => x = 0
So, the correct ordered pair is (0, 6).
