Solve the following word problem by writing an equation and solving it. Mary has 5 fewer CDs than Austin. Mary has 14 CDs. How many CDs does Austin have?
Let x be the amount Mary has and y the amount Austin has
$\displaystyle x = y-5$
It is known that $\displaystyle x=14$ so $\displaystyle 14=y-5$
It should not be hard to see that $\displaystyle y = 19$ and therefore Austin has 19 CDs
