    C.) 2 1/2

    Step-by-step explanation:

    X + 2 1/4 = 4 3/4

    Change the fractions to improper fractions.

    We have

    X + 9/4 = 19/4

    Subtract 9/4 from both sides

    X + 9/4 - 9/4 = 19/4 - 9/4

    X = 19/4 - 9/4

    Look for the LCM of the denominators.

    The LCM is 4

    Divide the LCM by the denominators and multiply the results by the numerators, the lcm becomes the denominator of the results.

    That's

    X = 19 - 9 / 4

    = 10/4

    Divide both numerator and denominator by 2

    = 5/2

    = 2 1/2

    C.) 2 1/2

    Step-by-step explanation:

    X+2 1/4=4 3/4

    Subtract 2 1/4 from each side

    X+2 1/4 - 2 1/4=4 3/4 - 2 1/4

    x = 2 2/4

    This simplifies to

    x = 2 1/2
