Answer 1

You can start by getting rid of the square root, those are ew

Answer 2

(Square both sides)

Answer 3

I understand how to do that part
It's just the part where you have to plug everything back in
I got (x+1) and (x+7)
which then becomes -1 and -7
when i plug them in i get radicals
and im confused about them

Answer 4

\[\sqrt{57 -8x } = x - 8 \]

like @dude said above square both sides

\[\left( \sqrt{57 - 8x} \right)^{2} = \left( x - 8 \right)^{2}\]

continue please from here ...
