Subproblem 1

Set the factor 'dxy' equal to zero and attempt to solve: Simplifying dxy = 0 Solving dxy = 0 Move all terms containing d to the left, all other terms to the right. Simplifying dxy = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(-1lny + lnx + 1)' equal to zero and attempt to solve: Simplifying -1lny + lnx + 1 = 0 Reorder the terms: 1 + lnx + -1lny = 0 Solving 1 + lnx + -1lny = 0 Move all terms containing d to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + lnx + -1 + -1lny = 0 + -1 Reorder the terms: 1 + -1 + lnx + -1lny = 0 + -1 Combine like terms: 1 + -1 = 0 0 + lnx + -1lny = 0 + -1 lnx + -1lny = 0 + -1 Combine like terms: 0 + -1 = -1 lnx + -1lny = -1 Add '-1lnx' to each side of the equation. lnx + -1lnx + -1lny = -1 + -1lnx Combine like terms: lnx + -1lnx = 0 0 + -1lny = -1 + -1lnx -1lny = -1 + -1lnx Add 'lny' to each side of the equation. -1lny + lny = -1 + -1lnx + lny Combine like terms: -1lny + lny = 0 0 = -1 + -1lnx + lny Simplifying 0 = -1 + -1lnx + lny The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
