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 :)
Solve In(5x+7) = 8. Round to the nearest thousandth.
Can someone walk me through this?

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

5x+7=e8
Subtract 7 from both sides of the equation.
5x=e8−7
Divide each term by 5 and simplify.
x=e85−75
