Solution for (y+ylnx)dx-(x-xy)dy=0 equation:


Simplifying
(y + ylnx) * dx + -1(x + -1xy) * dy = 0

Reorder the terms:
(lnxy + y) * dx + -1(x + -1xy) * dy = 0

Reorder the terms for easier multiplication:
dx(lnxy + y) + -1(x + -1xy) * dy = 0
(lnxy * dx + y * dx) + -1(x + -1xy) * dy = 0
(dlnx2y + dxy) + -1(x + -1xy) * dy = 0

Reorder the terms for easier multiplication:
dlnx2y + dxy + -1dy(x + -1xy) = 0
dlnx2y + dxy + (x * -1dy + -1xy * -1dy) = 0
dlnx2y + dxy + (-1dxy + 1dxy2) = 0

Combine like terms: dxy + -1dxy = 0
dlnx2y + 0 + 1dxy2 = 0
dlnx2y + 1dxy2 = 0

Solving
dlnx2y + 1dxy2 = 0

Solving for variable 'd'.

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

Factor out the Greatest Common Factor (GCF), 'dxy'.
dxy(lnx + y) = 0

Subproblem 1

Set the factor 'dxy' equal to zero and attempt to solve: Simplifying dxy = 0 Solving dxy = 0 Move all terms containing d to the left, all other terms to the right. Simplifying dxy = 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 '(lnx + y)' equal to zero and attempt to solve: Simplifying lnx + y = 0 Solving lnx + y = 0 Move all terms containing d to the left, all other terms to the right. Add '-1lnx' to each side of the equation. lnx + -1lnx + y = 0 + -1lnx Combine like terms: lnx + -1lnx = 0 0 + y = 0 + -1lnx y = 0 + -1lnx Remove the zero: y = -1lnx Add '-1y' to each side of the equation. y + -1y = -1lnx + -1y Combine like terms: y + -1y = 0 0 = -1lnx + -1y Simplifying 0 = -1lnx + -1y 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.
