(k+k)+(y+y)=

Solution for (k+k)+(y+y)= equation:

Simplifying
(k + k) + (y + y) = 0

Combine like terms: k + k = 2k
(2k) + (y + y) = 0
(2k) + (y + y) = 0

Combine like terms: y + y = 2y
(2k) + (2y) = 0
(2k) + (2y) = 0

Solving
(2k) + (2y) = 0

Solving for variable 'k'.

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

Add '(-2y)' to each side of the equation.
(2k) + (2y) + (-2y) = 0 + (-2y)

Combine like terms: (2y) + (-2y) = 0
(2k) + 0 = 0 + (-2y)
(2k) = 0 + (-2y)
Remove the zero:
(2k) = (-2y)

Divide each side by '2'.
k = (-1y)

Simplifying
k = (-1y)
