Please check-

Answers:

I think according to my calculations it would be 5, correct?

sqrt root of 7-x = 3-solve for x

Answers:

-2

2

4

-4

My choice would be 2

Is that correct-

I squared both sides and came out with 7-x = 9

and then x = 2

Thank you for taking the time to check this

5 is correct for

sqrt(2x + 15) = x

Notice that parentheses are required to show an expression correctly.

For the second one, would you like to double check:

7-x = 9,

x=?

or

does

7 - 2 = 9?
