    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
