Subproblem 1

Set the factor '(-9 + -1lnx)' equal to zero and attempt to solve: Simplifying -9 + -1lnx = 0 Solving -9 + -1lnx = 0 Move all terms containing l to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + -1lnx = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -1lnx = 0 + 9 -1lnx = 0 + 9 Combine like terms: 0 + 9 = 9 -1lnx = 9 Divide each side by '-1nx'. l = -9n-1x-1 Simplifying l = -9n-1x-1

Subproblem 2

Set the factor '(1 + -1lnx)' equal to zero and attempt to solve: Simplifying 1 + -1lnx = 0 Solving 1 + -1lnx = 0 Move all terms containing l to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1lnx = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1lnx = 0 + -1 -1lnx = 0 + -1 Combine like terms: 0 + -1 = -1 -1lnx = -1 Divide each side by '-1nx'. l = n-1x-1 Simplifying l = n-1x-1

Solution

l = {-9n-1x-1, n-1x-1}
