    I cancelled the x values and then cross multiplied but it gave me 1=-1 and I'm supposed to get x=1

    Since X^1/2 is X/2,

    and X^-1/2 is the same as 1/2X

    So X/2 = 1/2X

    2X^2 = 2

    X^2 = 2/2
    X^2 = 1

    Square root of one is 1,

    Therefore X = 1.

    You can’t cancel out because you have to simply it first, as in the first step I did.

    Hope that helps.

    What. Is. That?

    The proper way:
    x1/2 = x-1/2
    x1/2 = (x1/2)-1
    √x = 1/(√x)
    (√x)2 = 1
    x = 1

    How did u get X = X?

    My way is just a longer way so they can understand it, but the 2s cancel and x^2 = 1

    It's not longer, it's wrong. Revise the exponent rules.
    And x2 = 1 has two solutions anyway.
