    Answer:

    2, 4

    Step-by-step explanation:

    Ok so for this you have to substitute. y=4 so you put a 4 where the y is. This becomes

    4 – 3x = -2 We can already rule out (2,2) and (4,2) Why? Because the y is not a 4. So it’s gonna be either (0,4) or (2,4). Now, we have to find x. We have to isolate it. You do this by subtracting 4 from both sides.

    4 – 4 – 3x = -2 – 4 Now Simplify

    -3x = -6 Why -6? Because you can’t subtract a positive from a negative so it becomes -2 + -4. Since they are both negatives, you just add them together, then put the negative sign.

    Now divide -3 from both sides. Which becomes

    x = 2
