Subproblem 2
Set the factor '(lnxY + x + y)' equal to zero and attempt to solve:

Simplifying
lnxY + x + y = 0

Solving
lnxY + x + y = 0

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

Add '-1lnxY' to each side of the equation.
lnxY + x + -1lnxY + y = 0 + -1lnxY

Reorder the terms:
lnxY + -1lnxY + x + y = 0 + -1lnxY

Combine like terms: lnxY + -1lnxY = 0
0 + x + y = 0 + -1lnxY
x + y = 0 + -1lnxY
Remove the zero:
x + y = -1lnxY

Add '-1x' to each side of the equation.
x + -1x + y = -1lnxY + -1x

Combine like terms: x + -1x = 0
0 + y = -1lnxY + -1x
y = -1lnxY + -1x

Add '-1y' to each side of the equation.
y + -1y = -1lnxY + -1x + -1y

Combine like terms: y + -1y = 0
0 = -1lnxY + -1x + -1y

Simplifying
0 = -1lnxY + -1x + -1y
