Answer 7

move 1 over, square the equation, solve for x

Answer 8

It's equal to 1.

Answer 9

Thanks! How did you find it?

Answer 10

(x+3)^1 It-s always going to be the same number because u r multiplying.

So... I skiped that step. which was easier.

x+3/2-1=x
x/2 + 3/2 - 1 = X
Now u substract x/2 from both sides and u r going to end up with:

1/2= x-x/2
1/2 = 1/2x
Multiply 2 in both sides..
x=1

Answer 11

Thank you so much!

Answer 12

Anytime :)

Answer 13

Question, when you solved the (x+3)^1 part, did you know that the ^1 was supposed to be ^1/2?
Here it is in a pic. I am just double checking cuz you just said (x+3)^1, so I wasn't sure. Just making sure! Thanks a bunch. @lauluisa
