  1. no parenthesis are needed.

    5x+7=8

    I would take the 7 and subtract is from 7 and 8
    the new equation would look like this
    5x= 1

    then you would take 5/5 and 1/5 and then there’s your answer. I’m not the greatest at math but this is how I’d do it :)

  3. Thank you, but it's an equation dealing with natural logarithms.

  4. ln(5x+7) = 8
    5x+7 = e^8
    5x = e^8 - 7
    x = (e^7 - 7)/5

    just recall that ^ and log (or ln) are inverse operations, just like

    + and -
    * and /
    √ and ^2
    ...

  6. 5x+7=e8

    Subtract 7 from both sides of the equation.
    5x=e8−7

    Divide each term by 5 and simplify.
    x=e85−75
