    First, we multiply both sides by 2x to isolate the sqrt(x). We are then left with:

    -1/sqrt(x) = -x

    We can also multiply by (-1) to cancel out the negative on both sides. We can then square both sides to get:

    1/x = x^2

    Multiplying both sides by x yields:

    1 = x^3

    So, x = 1. You can check the solution to verify that x = 1 solves the equation.
