Solving for a variable means to rewrite the equation so that the desired variable is alone on one side. So, we have to "move" all the other variables/constants in order to make this happen. We are allowed to add/subtract the same quantity from both sides, or to multiply/divide both sides by any non-zero number.

Let's start with the first example: we are given

11. $d=rt$

the variable $r$ is not alone on the right hand side because it is multiplied by $t$ . We can reverse this by dividing both sides by $t$ : the equation becomes

$\dfrac{d}{t}=\dfrac{rt}{t}=r$

So, we have written the equation as $r=\frac{d}{t}$ , which means that $r$ now sits alone on one side of the equation, and thus we have solved the equation for $r$ !
