 Simplifying
4x + 4y = 0

 Solving
4x + 4y = 0

 Solving for variable 'x'.
 Move all terms containing x to the left, all other terms to the right.

 Add '-4y' to each side of the equation.
4x + 4y + -4y = 0 + -4y

 Combine like terms:
4y + -4y = 0
4x + 0 = 0 + -4y
4x = 0 + -4y

 Remove the zero:
4x = -4y

 Divide each side by '4'.
x = -1y

 Simplifying
x = -1y
