.23=ln(y)

Solution for .23=ln(y) equation:

Simplifying
0.23 = ln(y)

Multiply ln * y
0.23 = lny

Solving
0.23 = lny

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '-1lny' to each side of the equation.
0.23 + -1lny = lny + -1lny

Combine like terms: lny + -1lny = 0
0.23 + -1lny = 0

Add '-0.23' to each side of the equation.
0.23 + -0.23 + -1lny = 0 + -0.23

Combine like terms: 0.23 + -0.23 = 0.00
0.00 + -1lny = 0 + -0.23
-1lny = 0 + -0.23

Combine like terms: 0 + -0.23 = -0.23
-1lny = -0.23

Divide each side by '-1ny'.
l = 0.23n-1y-1

Simplifying
l = 0.23n-1y-1
