# Changing the Subject of an Equation

Changing the subject of an equation requires solving for the variable in question. This is possible even if we do not know the values of the variables. For example, in the relationship $$PV=nRT$$, we could solve for T in terms of the other values by dividing both sides by $$nR$$. Thus $$T = \frac{PV}{nR}$$.
