Hi there! Given the equation below.

$\large{r + \sqrt{x} = 9}$

First is to subtract both sides by r-term to isolate x-term.

$\large{r + \sqrt{x} - r = 9 - r} \\ \large{ \sqrt{x} = 9 - r}$

Because the x-term is in square root form. We have to square both sides to get rid of the square root.

$\large{( \sqrt{x})^{2} = {(9 - r)}^{2} } \\ \large{x = {(9 - r)}^{2} }$

Alternative Solution

$\large{x = {r}^{2} - 18r + 81}$

Answer

x = (9-r)² x = r²-18r+81

Both answers work. Any questions about this can be asked through comment.
