Question

Please please please help meeeeee

Answer 1

Answer:

x = -4

Step-by-step explanation:

Square both sides:

$(\sqrt{-5-2x})^2 =(\sqrt{-1-x} )^2$

The square root and the square will cancel to leave simply the argument within the square root:

-5 - 2x = -1 - x

Now simply isolate the variable x:

x = -5 + 1 = -4

Check to see if x = -4 will work:

$\sqrt{-5-2*(-4)} =\sqrt{-1-(-4)}$

$\sqrt{3} =\sqrt{3}$

This works, so we know that x = -4 is a solution.

Hope this helps!
