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


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

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

Reorder the terms:
((-1dxy + dx2) + 2y * (dx + -1dy)) = dx + dy
((-1dxy + dx2) + 2y * (dx + -1dy)) = dx + dy
(-1dxy + dx2 + (dx * 2y + -1dy * 2y)) = dx + dy
(-1dxy + dx2 + (2dxy + -2dy2)) = dx + dy

Reorder the terms:
(-1dxy + 2dxy + dx2 + -2dy2) = dx + dy

Combine like terms: -1dxy + 2dxy = 1dxy
(1dxy + dx2 + -2dy2) = dx + dy

Solving
1dxy + dx2 + -2dy2 = dx + dy

Solving for variable 'd'.

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

Add '-1dx' to each side of the equation.
1dxy + dx2 + -1dx + -2dy2 = dx + -1dx + dy

Reorder the terms:
-1dx + 1dxy + dx2 + -2dy2 = dx + -1dx + dy

Combine like terms: dx + -1dx = 0
-1dx + 1dxy + dx2 + -2dy2 = 0 + dy
-1dx + 1dxy + dx2 + -2dy2 = dy

Add '-1dy' to each side of the equation.
-1dx + 1dxy + dx2 + -1dy + -2dy2 = dy + -1dy

Combine like terms: dy + -1dy = 0
-1dx + 1dxy + dx2 + -1dy + -2dy2 = 0
