That statement is not true and is meaningless.
If 8-x = 19 then x = -11
The square root of -22 is not 19.

8-x = sqrt(2x+19), Is this what you want?
Domain: 19/2 ≤ x ≤ 8
Square both sides of the equation,
64-16x+x^2 = 2x+19
x^2-18x+45 = 0
(x-3)(x-15) = 0
x = 3, 15
Since 15 is outside the domain, the only solution is x = 3

Distribution into something interior the parentheses for the 1st concern. so which you get 2x+sixteen. Then subtract 6 from the two facets through fact to sparkling up X you should use the choice sign to get it on the different ingredient. x+6=2 x =6-2 x =4 i'm hoping this helped. If this didnt help, i'm so sorry I wasted it sluggish.

8-x=(square root ) 2x+19 <-- I assume you meant this
-11-x = sqrt(2x)
x^2+22x+121 = 2x
x^2 + 20x +121=0
x = [-20 +/- sqrt(400-484)]2
x = -10 +/- isqrt(21)
The roots are imaginary

hmm... go to hotmath.com
it will do the work for you if your on a stumped question
if it is a work sheet then i doesnt work. you can only use it if you have a math book.
]oh and you have to make some sort of username.
