    Answer:

    x = 2

    y = 4

    Step-by-step explanation:

    Since it gives you the “value” of y, just plug one of them into an equation:

    y = x + 2

    3x – 2 = x + 2

    Now, subtract x from both sides:

    3x – 2 = x + 2

    -x         – x

    __________

    2x – 2 = 2

    Then, add 2 to both sides:

    2x – 2 = 2

        + 2  + 2

    ________

    2x = 4

    Finally, divide both sides by 2:

    2x = 4

    x = 2

    Now to get y, just plug in 2 for x in an equation:

    y = x + 2

    y = 2 + 2

    y = 4
