(1 * dy + -1x * dy) + -1(y + -1) * dx = 0

Reorder the terms:
(-1dxy + 1dy) + -1(y + -1) * dx = 0
(-1dxy + 1dy) + -1(y + -1) * dx = 0

Reorder the terms:
-1dxy + 1dy + -1(-1 + y) * dx = 0

Reorder the terms for easier multiplication:
-1dxy + 1dy + -1dx(-1 + y) = 0
-1dxy + 1dy + (-1 * -1dx + y * -1dx) = 0
-1dxy + 1dy + (1dx + -1dxy) = 0

Reorder the terms:
1dx + -1dxy + -1dxy + 1dy = 0

Combine like terms: -1dxy + -1dxy = -2dxy
1dx + -2dxy + 1dy = 0

Solving
1dx + -2dxy + 1dy = 0

Factor out the Greatest Common Factor (GCF), 'd'.
d(x + -2xy + y) = 0

Subproblem 1

Set the factor 'd' equal to zero and attempt to solve: Simplifying d = 0 Solving d = 0 Move all terms containing d to the left, all other terms to the right. Simplifying d = 0

Subproblem 2

Set the factor '(x + -2xy + y)' equal to zero and attempt to solve: Simplifying x + -2xy + y = 0 Solving x + -2xy + y = 0 Move all terms containing d to the left, all other terms to the right. Add '-1x' to each side of the equation. x + -2xy + -1x + y = 0 + -1x Reorder the terms: x + -1x + -2xy + y = 0 + -1x Combine like terms: x + -1x = 0 0 + -2xy + y = 0 + -1x -2xy + y = 0 + -1x Remove the zero: -2xy + y = -1x Add '2xy' to each side of the equation. -2xy + 2xy + y = -1x + 2xy Combine like terms: -2xy + 2xy = 0 0 + y = -1x + 2xy y = -1x + 2xy Add '-1y' to each side of the equation. y + -1y = -1x + 2xy + -1y Combine like terms: y + -1y = 0 0 = -1x + 2xy + -1y Simplifying 0 = -1x + 2xy + -1y The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
