Answer:

4. 2x=-2

4. Multiplication property of equality

Step-by-step explanation:

The multiplication property of equality states that if you multiply a number to one side, you must multiply it by the other. This property allows you to solve division equations. For example, if x/4 = 2, multiply both sides by 4 to get x = 8.
