Solution for (x+y-3)dx=(x-y-1)dy equation:


Simplifying
(x + y + -3) * dx = (x + -1y + -1) * dy

Reorder the terms:
(-3 + x + y) * dx = (x + -1y + -1) * dy

Reorder the terms for easier multiplication:
dx(-3 + x + y) = (x + -1y + -1) * dy
(-3 * dx + x * dx + y * dx) = (x + -1y + -1) * dy

Reorder the terms:
(-3dx + dxy + dx2) = (x + -1y + -1) * dy
(-3dx + dxy + dx2) = (x + -1y + -1) * dy

Reorder the terms:
-3dx + dxy + dx2 = (-1 + x + -1y) * dy

Reorder the terms for easier multiplication:
-3dx + dxy + dx2 = dy(-1 + x + -1y)
-3dx + dxy + dx2 = (-1 * dy + x * dy + -1y * dy)

Reorder the terms:
-3dx + dxy + dx2 = (dxy + -1dy + -1dy2)
-3dx + dxy + dx2 = (dxy + -1dy + -1dy2)

Add '-1dxy' to each side of the equation.
-3dx + dxy + -1dxy + dx2 = dxy + -1dy + -1dxy + -1dy2

Combine like terms: dxy + -1dxy = 0
-3dx + 0 + dx2 = dxy + -1dy + -1dxy + -1dy2
-3dx + dx2 = dxy + -1dy + -1dxy + -1dy2

Reorder the terms:
-3dx + dx2 = dxy + -1dxy + -1dy + -1dy2

Combine like terms: dxy + -1dxy = 0
-3dx + dx2 = 0 + -1dy + -1dy2
-3dx + dx2 = -1dy + -1dy2

Solving
-3dx + dx2 = -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.
-3dx + dx2 + dy = -1dy + dy + -1dy2

Combine like terms: -1dy + dy = 0
-3dx + dx2 + dy = 0 + -1dy2
-3dx + dx2 + dy = -1dy2

Add 'dy2' to each side of the equation.
-3dx + dx2 + dy + dy2 = -1dy2 + dy2

Combine like terms: -1dy2 + dy2 = 0
-3dx + dx2 + dy + dy2 = 0

Factor out the Greatest Common Factor (GCF), 'd'.
d(-3x + x2 + 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
