<h3>First let's write our equation</h3><h3 /><h3>

</h3><h3 /><h3>Reduce</h3>
<em>Definition - </em><em>reduction refers to the rewriting of an expression into a simpler form</em>
<h3 />
We can reduce
to 
Our equation is now 
Now we can cross multiply
<em>Definition - </em><em>given an equation between two fractions or rational expressions, one can cross-multiply to simplify the equation or determine the value of a variable.</em>

<h3>Add</h3>
We are adding because we want our variable to be on one side of the equation

<h3>To check we can show our equation but instead of d we have 18</h3><h3 />

Subtract and we get

Which makes it true
<h3><em>Have a good day!</em></h3>
When functions are defined by more then one equation, they are called piecewise defined functions
