    To solve this question, all you have to do is take 2 raise it to 3, and make it equal to the expression 3x-7 and solve for x.

    2^3=3x-7

    8=3x-7

    8+7=3x

    15=3x

    15/3=3x/3

    5=x.

    X=5.

    You can verify if the answer is correct by plugging the value of 5 back into the original logarithmic equation.
