You have to divide both sides by \(\Large \sqrt{2}\), then rationalize the denominator (if the book requires you to do it)

idk i suck at square rooting stuff

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
It's just simply \[\Large x = \frac{5}{\sqrt{2}}\] optionally you can rationalize the denominator to get \[\Large x = \frac{5\sqrt{2}}{2}\]
