    Replace y with 15

    The equation is now:

    1x - 15 = 30

    Add 15 to both sides:

    1x = 45

    Divide both sides by 1

    X = 45

    Answer: X = 45

    Step-by-step explanation:

    1x - 15 = 30

    add 15 to both sides

    1x = 30 + 15

    1x = 45

    then you have to seperate the 1 from the x, so divide 1 from both sides

    45 divided by 1 = 45

    so the answer is x = 45
