Solution for (x+1)dy=-(y-2)dx equation:


Simplifying
(x + 1) * dy = -1(y + -2) * dx

Reorder the terms:
(1 + x) * dy = -1(y + -2) * dx

Reorder the terms for easier multiplication:
dy(1 + x) = -1(y + -2) * dx
(1 * dy + x * dy) = -1(y + -2) * dx

Reorder the terms:
(dxy + 1dy) = -1(y + -2) * dx
(dxy + 1dy) = -1(y + -2) * dx

Reorder the terms:
dxy + 1dy = -1(-2 + y) * dx

Reorder the terms for easier multiplication:
dxy + 1dy = -1dx(-2 + y)
dxy + 1dy = (-2 * -1dx + y * -1dx)
dxy + 1dy = (2dx + -1dxy)

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

Solving for variable 'd'.

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

Add '-2dx' to each side of the equation.
dxy + -2dx + 1dy = 2dx + -2dx + -1dxy

Reorder the terms:
-2dx + dxy + 1dy = 2dx + -2dx + -1dxy

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

Add 'dxy' to each side of the equation.
-2dx + dxy + dxy + 1dy = -1dxy + dxy

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

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

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