Question

u−4= Square Root of −3u+22 solve for u where u is a real number

Answer 1

is it 6?

Answer 2

First, You need to square both sides so you can easily solve it.
\[(u-4)^{2}= (\sqrt{-3u+22})^{2}\]
By squaring, the square root will be cancelled.

Answer 3

I agree after you square it get the u's on both sides and factor them out so that the u is by it's self.
