    The answer is 10.

    Step-by-step explanation:

    Multiply both sides of the equation by 12.

    12 (3/4x - 5/6) = 12 times 2/3x.

    Distribute 12 through the parenthesis.

    12 times 3/4x - 12 times 5/6 = 12 times 2/3x.

    Reduce the numbers with greatest common divisor 3.

    12 times 3/4x - 12 times 5/6 = 4 times 2x.

    Reduce the numbers with greatest common divisor 4.

    3 times 3x - 12 times 5/6 = 4 times 2x.

    Reduce the numbers with greatest common divisor 6.

    3 times 3x - 2 times 5 = 4 times 2x.

    Calculate the product, 4 times 2x.

    3 times 3x - 2 times 5 = 8x.

    Calculate the product 3 times 3x.

    9x - 2 times 5 = 8x.

    Multiply the numbers - 2 times 5.

    9x - 10 = 8x.

    Move the constant to the right by adding its opposite to both sides.

    9x - 10 + 10 = 8x + 10.

    Eliminate the opposites, - 10 + 10.

    9x = 8x + 10.

    Move the variable to the left by adding its opposite to both sides.

    9x - 8x = 8x - 8x + 10.

    Now eliminate the opposites

    9x - 8x = 10.

    Collect the like terms by subtracting their coefficients.

    (9-8) x

    Subtract the numbers.

    1x.

    When the term has a coefficient of 1, it doesn't have to be written, so it's basically x.

    Then, x will equal to 10!
