Solve the logarithmic equation. Be sure to reject any value that is not in the domain of the original logarithmic expressions. Give the exact answer.

ln sqrt x+6 = 9 i got {e^9-6}

log (x + 4) = log (5x - 5)
i got: 9/4

log (x + 30) - log 2 = log (3x + 2)
i got: {58}

    Please limit yourself to one question per post, and show your work

    log (x + 4) = log (5x - 5)

    As long as the bases of both logs are the same,

    x + 4 = 5x - 5
    4x = 9
    x = 9/4
    =======================
    log (x + 30) - log 2 = log (3x + 2)
    (x+30)/2 = (3x+2)
    x + 30 = 6x + 4
    5x = 26
    x = 5.2
