Solve for x:
ln(4 x - 2) = 4

Cancel logarithms by taking exp of both sides:
4 x - 2 = e^4

Add 2 to both sides:
4 x = e^4 + 2

Divide both sides by 4:
Answer: x = e^4/4 + 1/2 =~14.1495....

ln(4x-2)=4

(4x-2) = e^4                                                          and e^4= 54.598

4x-2 = 54.598

4x    = 56.598

  x   = 14.1495
