ln%285-4x%29=1 Start with the given equation.


5-4x=e%5E1 Convert to exponential form


5-4x=e Evaluate 'e' to the first power to get 'e'


-4x=e-5 Subtract 5 from both sides.


x=%28e-5%29%2F%28-4%29 Divide both sides by -4 to isolate x.


x=-%28e-5%29%2F4 Simplify.


----------------------------------------------------------------------

Answer:

So the solution is x=-%28e-5%29%2F4

solve the equation for x.
ln(5-4x)=1
---
base = e
exponent = 1
result = 5-4x
----
5-4x = e^1
4x = 5-e
---
x = 0.5704..
