We are given expression:
.
In order to simplify given expression, let us break it into smaller parts.
![\frac{28}{12} = \frac{7}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B12%7D%20%3D%20%5Cfrac%7B7%7D%7B3%7D)
![\frac{p^9}{p^{-6}} =p^{9-(-6)} = p^{9+6} = p^{15}.](https://tex.z-dn.net/?f=%5Cfrac%7Bp%5E9%7D%7Bp%5E%7B-6%7D%7D%20%3Dp%5E%7B9-%28-6%29%7D%20%3D%20p%5E%7B9%2B6%7D%20%3D%20p%5E%7B15%7D.)
![\frac{q^{-5}}{q^7} =\frac{1}{q^{7-(-5)}} = \frac{1}{q^{7+5}} = \frac{1}{q^{12}}](https://tex.z-dn.net/?f=%5Cfrac%7Bq%5E%7B-5%7D%7D%7Bq%5E7%7D%20%3D%5Cfrac%7B1%7D%7Bq%5E%7B7-%28-5%29%7D%7D%20%3D%20%5Cfrac%7B1%7D%7Bq%5E%7B7%2B5%7D%7D%20%3D%20%5Cfrac%7B1%7D%7Bq%5E%7B12%7D%7D)
Combining all terms together, we get
![\frac{7p^{15}}{3q^{12}} .](https://tex.z-dn.net/?f=%5Cfrac%7B7p%5E%7B15%7D%7D%7B3q%5E%7B12%7D%7D%20.)
<h3>Therefore, final expression is
![\frac{7p^{15}}{3q^{12}}.](https://tex.z-dn.net/?f=%5Cfrac%7B7p%5E%7B15%7D%7D%7B3q%5E%7B12%7D%7D.)

Lydia is the first equation. She bought 5 pounds of apples which is x and bought 3 pounds of bananas which is y. Basically, remember each banana and apple weighs a price per pound. We don't know the price so we just put an x. This is the same for the second equation
