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


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

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

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

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

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

Reorder the terms:
-2dx + dxy = (dxy + -1dy + -1dy2)
-2dx + dxy = (dxy + -1dy + -1dy2)

Add '-1dxy' to each side of the equation.
-2dx + dxy + -1dxy = dxy + -1dy + -1dxy + -1dy2

Combine like terms: dxy + -1dxy = 0
-2dx + 0 = dxy + -1dy + -1dxy + -1dy2
-2dx = dxy + -1dy + -1dxy + -1dy2

Reorder the terms:
-2dx = dxy + -1dxy + -1dy + -1dy2

Combine like terms: dxy + -1dxy = 0
-2dx = 0 + -1dy + -1dy2
-2dx = -1dy + -1dy2

Solving
-2dx = -1dy + -1dy2

Solving for variable 'd'.

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

Add 'dy' to each side of the equation.
-2dx + dy = -1dy + dy + -1dy2

Combine like terms: -1dy + dy = 0
-2dx + dy = 0 + -1dy2
-2dx + dy = -1dy2

Add 'dy2' to each side of the equation.
-2dx + dy + dy2 = -1dy2 + dy2

Combine like terms: -1dy2 + dy2 = 0
-2dx + dy + dy2 = 0

Factor out the Greatest Common Factor (GCF), 'd'.
d(-2x + y + y2) = 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 + y + y2)' equal to zero and attempt to solve: Simplifying -2x + y + y2 = 0 Solving -2x + y + y2 = 0 Move all terms containing d to the left, all other terms to the right. Add '2x' to each side of the equation. -2x + y + 2x + y2 = 0 + 2x Reorder the terms: -2x + 2x + y + y2 = 0 + 2x Combine like terms: -2x + 2x = 0 0 + y + y2 = 0 + 2x y + y2 = 0 + 2x Remove the zero: y + y2 = 2x Add '-1y' to each side of the equation. y + -1y + y2 = 2x + -1y Combine like terms: y + -1y = 0 0 + y2 = 2x + -1y y2 = 2x + -1y Add '-1y2' to each side of the equation. y2 + -1y2 = 2x + -1y + -1y2 Combine like terms: y2 + -1y2 = 0 0 = 2x + -1y + -1y2 Simplifying 0 = 2x + -1y + -1y2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
