    I'm unclear on your question.

    Option 1 — x = 2¼ (mixed number)

    Plug in x = 2¼:

    = 12(2¼) + 6

    = 12(2 + ¼) + 6

    = 24 + 3 + 6

    = 33

    Option 2 —you want two answer, one for x = 2 and another for x = ¼:

    Plug in x = 2:

    = 12(2) + 6

    = 24 + 6

    = 30

    Plug in x = ¼:

    = 12(¼) + 6

    = 3 + 6

    = 9

    Answers:

    If you want one answer for x = 2¼

    x = 2¼ --> 12x + 6 = 33

    If you want two answers (one for x = 2 and another for x = ¼)

    x = 2 --> 12x + 6 = 30

    x = ¼ --> 12x + 6 = 9

    For x = 2, just plug in two where x is:

    12(2) + 6

    24 + 6

    30

    Thirty is your new expression.

    ________________________

    For x = 1/4 , just plug in one-fourth where x is:

    12(1/4) + 6

    Recall that whole numbers multiply into the numerator when being multiplied to a fraction. Keeping this in mind, finish up the process:

    12/4 + 6

    Four goes into twelve three times, so this will become:

    3 + 6

    9

    Nine is your new expression.

    x = 2 1/4

    12(2 1/4) + 6 = (24 + 3) + 6 = 33

      I don't believe he meant it as a mixed fraction. I think he wanted two separate instances of substitution. However, Cutler if you're reading this and you actually meant to write x = 2¼ then this is your answer instead. I doubt that's what you intended to write though.
