Solution for ydx=3(x+y)dy equation:


Simplifying
ydx = 3(x + y) * dy

Reorder the terms for easier multiplication:
dxy = 3dy(x + y)
dxy = (x * 3dy + y * 3dy)
dxy = (3dxy + 3dy2)

Solving
dxy = 3dxy + 3dy2

Solving for variable 'd'.

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

Add '-3dxy' to each side of the equation.
dxy + -3dxy = 3dxy + -3dxy + 3dy2

Combine like terms: dxy + -3dxy = -2dxy
-2dxy = 3dxy + -3dxy + 3dy2

Combine like terms: 3dxy + -3dxy = 0
-2dxy = 0 + 3dy2
-2dxy = 3dy2

Add '-3dy2' to each side of the equation.
-2dxy + -3dy2 = 3dy2 + -3dy2

Combine like terms: 3dy2 + -3dy2 = 0
-2dxy + -3dy2 = 0

Factor out the Greatest Common Factor (GCF), '-1dy'.
-1dy(2x + 3y) = 0

Ignore the factor -1.

Subproblem 1

Set the factor 'dy' equal to zero and attempt to solve: Simplifying dy = 0 Solving dy = 0 Move all terms containing d to the left, all other terms to the right. Simplifying dy = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(2x + 3y)' equal to zero and attempt to solve: Simplifying 2x + 3y = 0 Solving 2x + 3y = 0 Move all terms containing d to the left, all other terms to the right. Add '-2x' to each side of the equation. 2x + -2x + 3y = 0 + -2x Combine like terms: 2x + -2x = 0 0 + 3y = 0 + -2x 3y = 0 + -2x Remove the zero: 3y = -2x Add '-3y' to each side of the equation. 3y + -3y = -2x + -3y Combine like terms: 3y + -3y = 0 0 = -2x + -3y Simplifying 0 = -2x + -3y The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
