Find x

Given x^2/(3^2) = 3/x, find x.

I quickly think of cross-multiplication.

(x^2)(x) = (3^2)(3)

x^3 = 9 • 3

x^3 = 27

Take the cube root on.both sides of the equation.

cuberoot{x^3} = cuberoot{27}

x = 3

Of course, not all questions will be this simple but returning to basic math occasionally is a good idea.
