Solving
0.78 = 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.
0.78 + -1lny = lny + -1lny

Combine like terms: lny + -1lny = 0
0.78 + -1lny = 0

Add '-0.78' to each side of the equation.
0.78 + -0.78 + -1lny = 0 + -0.78

Combine like terms: 0.78 + -0.78 = 0.00
0.00 + -1lny = 0 + -0.78
-1lny = 0 + -0.78

Combine like terms: 0 + -0.78 = -0.78
-1lny = -0.78

Divide each side by '-1ny'.
l = 0.78n-1y-1

Simplifying
l = 0.78n-1y-1
