Solution for x*dx=y*dy equation:


Simplifying
x * dx = y * dy

Multiply x * dx
dx2 = y * dy

Multiply y * dy
dx2 = dy2

Solving
dx2 = dy2

Solving for variable 'd'.

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

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

Combine like terms: dy2 + -1dy2 = 0
dx2 + -1dy2 = 0

Factor out the Greatest Common Factor (GCF), 'd'.
d(x2 + -1y2) = 0

Factor a difference between two squares.
d((x + y)(x + -1y)) = 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 + y)' equal to zero and attempt to solve: Simplifying x + y = 0 Solving x + 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 + -1x + y = 0 + -1x Combine like terms: x + -1x = 0 0 + y = 0 + -1x y = 0 + -1x Remove the zero: y = -1x Add '-1y' to each side of the equation. y + -1y = -1x + -1y Combine like terms: y + -1y = 0 0 = -1x + -1y Simplifying 0 = -1x + -1y The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 3

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