Question

What is the solution to the equation -√(15+x)=-3?

Answer 1

So, the negative would be divided out to make it 3, then square both sides to get rid of the square root and get 9, then subtract 15 and you get -6.  <span />

Answer 2

X=-6

Plug in  -6 for  x 
√15+(-6) = 3
Simplify
√9 = 3
Solution is x=-6
