Algebraic symbol manipulation

Capacitive reactance in an electrical circuit to an alternating current is given by

,
where is frequency of the current and is capacitance of the circuit.

Solve for .

In order to solve for C, we need to get it out of the denominator of the expression on the right side.

To do this mulitply both sides of the equation by C.

This gives

Now divide both sides by Xc.
