    M/2 - 5 + 3 = 2

    Put each term in m/2 - 5 + 3 over the common denominator 2: m/2 - 5 + 3 = m/2 - 10/2 + 6/2:

    m/2 - 10/2 + 6/2 = 2

    m/2 - 10/2 + 6/2 = (m - 10 + 6) / 2:

    (m - 10 + 6) / 2 = 2

    Subtract like terms. 6 - 10 = - 4:

    (m - 4) / 2 = 2

    Multiply both sides of (m - 4) / 2 = 2 by 2:

    (2 (m - 4)) / 2 = 2*2

    (2 (m - 4)) / 2 = 2/2 * (m - 4) = m - 4:

    m - 4 = 2*2

    2*2 = 4:

    m - 4 = 4

    Add 4 to both sides:

    m + (4 - 4) = 4 + 4

    4 - 4 = 0:

    m = 4 + 4

    4 + 4 = 8:

    Answer: m = 8
