Ответ:
Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation. Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation. Raising both sides of the equation to the same odd power or taking the same odd root will produce an equivalent equation.
