In solving 2x – 5 = 3, do you have to use the addition property of equality first? why or why not? why do you normally use the addition property of equality first?

No; you can use the multiplication property of equality first, multiplying through by 1/2, but you have to distribute. Using the addition property first means you don't have to distribute, which sometimes means that using the addition property is easier.

Step-by-step explanation:
