move the -x from the right to the left of the equality. We get x - (- x) = 0 Open the brackets, minus by minus gives plus x + x = 0, we add 2x = 0, respectively, and we find x = 0/2, respectively, x = 0.

First, move the -x to the left of the expression. With this, we get: x - (- x) = 0. Next, you should open the brackets. Since minus by minus gives plus, it turns out x + x = 0. We carry out the addition, we get 2x = 0. The result is x = 0/2, where x = 0.
