Solution for -x-y+k(x+y)=0 equation:


Simplifying
-1x + -1y + k(x + y) = 0
-1x + -1y + (x * k + y * k) = 0
-1x + -1y + (kx + ky) = 0

Reorder the terms:
kx + ky + -1x + -1y = 0

Solving
kx + ky + -1x + -1y = 0

Solving for variable 'k'.

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

Add 'x' to each side of the equation.
kx + ky + -1x + x + -1y = 0 + x

Combine like terms: -1x + x = 0
kx + ky + 0 + -1y = 0 + x
kx + ky + -1y = 0 + x
Remove the zero:
kx + ky + -1y = x

Add 'y' to each side of the equation.
kx + ky + -1y + y = x + y
