Answer 1

Answer:

x2-4=5

   +4 +4

x2=9

square root both the x and 9

x=3

Answer 2

Answer:

x2 - 4=5

      +4 +4

     x2 = 9

           x=+-3

Step-by-step explanation:

What you do is add 4 on each side because, you do the same thing that you did to the other side so you'll add 5+4=9 so you'll have 2x=9 and then you will take the square root of 9 and then you will get you're answer which is x=3.

I hope this helped y'all!!!!!
