Solve the equation, using the domain of x = {-1, 0, 2}. Write your solutions as a set of ordered pairs listed from least to greatest based on the x value. Do not type any spaces. Where needed, round to two decimal places.

    Given:

    x = { - 1, 0, 2}

    2x + 3y = 7

    3y = - 2x + 7

    y = (-2x + 7) / 3

    Now,

    Lets substitute the every "x" value in the equation.

    For x = - 1

    y = (-2 (-1) + 7) / 3

    y = 3

    For x = 0

    y = (-2 (0) + 7) / 3

    y = 2.33

    For x = 2

    y = (-2 (2) + 7) / 3

    y = 1

    So,

    Range (y) = {3, 2.33, 1}

    So,

    The answer in ordered pairs is { (-1, 3), (0, 2.33), (2, 1) }
