    You had it right I believe, what exactly is your question?

    sin(5x-24) = 0.6

    5x - 24 = arcsin(0.6)

    5x = 24 + arcsin(0.6)

    x = [24 + arcsin(0.6)] / 5

    X = ~12.174

    Or, if (5x-24) is measured in radians, x is about 4.93.

    There should be an infinite number of solutions, shouldn't there? Remember that the range of the arcsin function is only [-π/2, π/2].
