log(x+10)=1+log(4x-3)

  • College Algebra -

    Log(x+10) = 1 + Log(4x-3).
    Log(x+10)-Log(4x-3) = 1.
    Log(x+10)/Log(4x-3) = 1.
    Cross multiply:
    Log(x+10) = Log(4x-3).
    If 2 numbers have equal Logs, the numbers are equal:
    x+10 = 4x-3.
    4x-x = 10+3.
    3x = 13.
    X = 13/3.
