    x = 77/2

    Step-by-step explanation:

    Solve for x:

    4 x - (2 x) / 3 - 3 x - 5 - 3/2 - 4/3 = 5

    Put each term in 4 x - (2 x) / 3 - 3 x - 5 - 3/2 - 4/3 over the common denominator 6: 4 x - (2 x) / 3 - 3 x - 5 - 3/2 - 4/3 = (24 x) / 6 - (4 x) / 6 - (18 x) / 6 - 30/6 - 9/6 - 8/6:

    (24 x) / 6 - (4 x) / 6 - (18 x) / 6 - 30/6 - 9/6 - 8/6 = 5

    (24 x) / 6 - (4 x) / 6 - (18 x) / 6 - 30/6 - 9/6 - 8/6 = (24 x - 4 x - 18 x - 30 - 9 - 8) / 6:

    (24 x - 4 x - 18 x - 30 - 9 - 8) / 6 = 5

    Grouping like terms, 24 x - 4 x - 18 x - 30 - 9 - 8 = (24 x - 4 x - 18 x) + (-9 - 30 - 8):

    ((24 x - 4 x - 18 x) + (-9 - 30 - 8)) / 6 = 5

    24 x - 4 x - 18 x = 2 x:

    (2 x + (-9 - 30 - 8)) / 6 = 5

    -9 - 30 - 8 = - 47:

    (2 x + - 47) / 6 = 5

    Multiply both sides of (2 x - 47) / 6 = 5 by 6:

    (6 (2 x - 47)) / 6 = 6*5

    (6 (2 x - 47)) / 6 = 6/6 * (2 x - 47) = 2 x - 47:

    2 x - 47 = 6*5

    6*5 = 30:

    2 x - 47 = 30

    Add 47 to both sides:

    2 x + (47 - 47) = 47 + 30

    47 - 47 = 0:

    2 x = 30 + 47

    30 + 47 = 77:

    2 x = 77

    Divide both sides of 2 x = 77 by 2:

    (2 x) / 2 = 77/2

    2/2 = 1:

    Answer: x = 77/2
